Paul Nothaft 975a815f99 Merge branch 'beta' into fix/email-normalization-574
Resolves a conflict with the CRM merge (#555) that landed on beta
between when this branch was cut and now.

Two conflict regions in backend/src/routes/adminCustomers.js:

1. **Require block** — both branches added new requires after
   customerAccountsService. Kept both: this branch's
   emailNormalization import AND beta's customerHoursService +
   invoiceService imports (the CRM merge added the hours-billing +
   invoice-creation paths to this router).

2. **Edit-customer validators** — both branches changed the same set
   of body() validators in the PUT /:id handler. This branch added
   the IDENTITY_PRESERVING_NORMALIZE_EMAIL options arg to
   normalizeEmail; beta changed every body() to optional({ nullable:
   true }) so passive-customer records that store nulls for missing
   profile fields don't reject on save. Kept both: the nullable
   pattern from beta + the email-normalization options from this
   branch. Preserved beta's explanatory comment about the nullable
   choice.

Also patched one NEW normalizeEmail site the CRM merge introduced:

- backend/src/routes/adminCustomers.js:231 — POST /admin/customers
  now exists (CRM-era customer-create endpoint). Same options arg
  applied.

backend/src/routes/adminBusinessProfile.js has an isEmail() WITHOUT
normalizeEmail() on the issuer email — intentional (no normalization
means no risk of the Gmail dot-strip bug for that field), no change
needed.

All 18 normalizeEmail sites now pass IDENTITY_PRESERVING_NORMALIZE_EMAIL.
7/7 regression tests still pass. Lint clean on the merged file.

Paul Nothaft 075b45f020 fix(email): preserve dots + subaddresses across all normalization sites (#574)
Closes #574.

Reporter (@blazmaric) identified the root cause cleanly:
express-validator's `.normalizeEmail()` applies provider-specific
canonicalization by default — Gmail dot-stripping, +tag stripping,
googlemail → gmail folding, etc. That's wrong for identity: PicPeak
uses email as a login identifier, so `john.doe@gmail.com` getting
silently stored as `johndoe@gmail.com` means the user can't log in
with the address they were invited with.

The bug existed at 17 call sites across the codebase (auth, admin user
create/update, customer create/update, event create/update on three
different routes, customer login, feedback submission). All of them
are identity-bearing — none had a legitimate reason to strip dots
for deduplication.

Fix: introduce one shared options object in `utils/emailNormalization`
disabling every provider-specific normalization
(gmail_remove_dots, gmail_remove_subaddress,
gmail_convert_googlemaildotcom, outlookdotcom_remove_subaddress,
yahoo_remove_subaddress, icloud_remove_subaddress). The only default
left enabled is `all_lowercase`, which is safe — local-parts are
case-insensitive in practice on every major provider, and lowercasing
keeps login lookup consistent.

Every call site updated to pass the shared options. 7 unit tests pin
the preserved-dots, preserved-subaddress, preserved-googlemail-domain,
and still-lowercase behaviours so a future refactor can't silently
regress.

## Migration note

Existing accounts whose emails were already stripped before this fix
remain with the stripped form in the DB. The fix takes effect for new
invitations going forward. If an admin re-invites an existing user
with the un-stripped address, that would create a duplicate account —
out of scope here; if it becomes a real problem we can add a
backward-compat login fallback (try lookup with dot-stripped form too)
as a separate change.

Luca d543949188 feat(crm): backend code — services + routes + utilities + tests
Brings in the full backend CRM stack on top of the consolidated
migration (60abe8c).

Services (CRM)
  - quoteService — full lifecycle (draft → sent → accepted → converted
    to event/invoice), Skonto + Storno + reissue paths
  - invoiceService — spawnInstallmentInvoices, updateInstallmentPlan,
    monthly-billing accumulator, payment-check tokens, dunning ladder
  - contractService — block-composable contract editor, in-browser
    signature flow, wet-PDF upload path, integrity check, audit trail
  - customerHoursService — per-entry locking, billing integration
  - dealsService — cross-document lineage (deal_uuid)
  - taxReportService — quarterly aggregates + CSV/PDF export
  - eventReminderService — pre-event customer reminder cron pass
  - _renderContext — shared issuer/recipient blocks across PDF types
  - pdfService extensions — custom-font registration, font picker

Routes (admin + public)
  - adminQuotes, adminInvoices, adminContracts, adminCalendar,
    adminDeals, adminTaxReport, adminDev, adminBusinessProfile
  - publicQuotes (accept/decline), publicContracts (sign),
    publicPaymentCheck
  - Extensions on adminEvents, adminCustomers, adminSettings,
    adminEmail, adminFeatureFlags, adminThumbnails, adminPhotos,
    adminCategories, adminUsers, adminArchives, adminDashboard
  - server.js wires the new mounts (kept upstream's noStoreCache on
    customer routes per 3-way merge)

Utilities
  - schemaCache (cached hasColumn lookups across services)
  - documentSequences (atomic gap-free numbering — §14 UStG)
  - safePath (path-containment guards at fs stream boundaries)
  - clientIp (sanctioned XFF reader for audit logs)
  - publicTokenGuards (pre-multer token validation + attempt counters)
  - numericHelpers (ensureInt / ensureNumber consolidation)
  - dateFormatter (formatShortDate + dateInputLang)
  - dbCompat extensions, iban + pdfFilename helpers, resolveLogoFile

Infrastructure
  - Bundled PDF fonts (Comic-Neue / IBM-Plex-Sans / Inter / Jost /
    Montserrat / Noto-Sans / Playfair-Display / Poppins)
  - Backend package.json + lock updates (pdfkit, signature_pad,
    qrcode, et al.)
  - Sample storage layout under storage/business-docs/quote/

Tests
  - 14 new test files covering quote/invoice/contract lifecycle,
    installment plan reshape, line-item hierarchy, customer hours,
    payment check, tax report PDF, IBAN parsing, filename sanitiser

Paul Nothaft 7eeef2ba98 feat(downloads): preserve original camera filenames on download (opt-in) (#493)
New Settings → General toggle `Use original filenames on download` (off by
default). When on, single-photo downloads, bulk/selection zips, and per-event
archive zips surface `photos.original_filename` instead of the sanitized
storage filename. Storage paths are unchanged.

- Content-Disposition uses RFC 5987 (`filename=` ASCII + `filename*=UTF-8''…`)
  so unicode camera filenames survive while header-injection bytes are stripped.
- Zip entries are deduplicated with a deterministic `_1` / `_2` suffix on
  collision (folder structure preserved in archive zips).
- Pre-generated download-all zips and the in-memory setting cache are
  invalidated when the toggle flips so the next download rebuilds with the
  new names.
- Falls back to the storage filename whenever `original_filename` is null
  (legacy uploads predating migration 062).

Paul Nothaft e8052adf1d fix(email): render conditionals, localise password placeholders, fix caller/template variable drift
Bundle of email-renderer and email-caller fixes triggered by a
reproducer on picpeak.nothaft.cloud (gallery_created mail showing
literal `{{#if welcome_message}}` markers and `Passwort: (set at
creation)`). The audit that followed surfaced six more user-visible
defects in the same surface; all are fixed here so customer-facing
mail renders cleanly.

Renderer (`backend/src/services/emailProcessor.js`)

- `safeTemplateReplace` now resolves `{{#if VAR}}…{{/if}}` blocks
  before flat `{{var}}` substitution. The shipped templates have used
  Handlebars-style conditionals since migration 026; the renderer
  ignored them, so the markers leaked verbatim into every mail with
  an empty welcome_message. Lifted to module scope and exported so
  the conditional contract is unit-testable. Single-pass, non-nested
  (commented).

- Added `passwordSetAtCreationI18n` next to the existing two i18n
  password sentinels so `(set at creation)` (sent by the publish-
  from-draft flow when only the bcrypt hash remains) is localised
  to "Das bei der Erstellung der Galerie gesetzte Passwort" /
  equivalent in EN/DE/NL/PT/RU instead of the raw English string.

- Added an opt-in `{ escapeHtml: true }` mode to `safeTemplateReplace`
  so admin-supplied free text (`event_name`, `host_name`, …) is
  HTML-escaped on substitution into the HTML body. Allowlist of
  passthrough keys (`welcome_message` already-HTML, server-generated
  URLs `gallery_link` / `client_link`). Subject and text body keep
  the legacy unescaped behaviour. `formatWelcomeMessage` now escapes
  before nl2br so the welcome_message allowlist is safe.

- New `htmlToText()` strips `<style>` and `<script>` blocks (and
  their content) before tag-stripping, decodes common entities, and
  collapses whitespace. Used by the textBody fallback in
  `sendTemplateEmail` — without this, every template missing a
  `body_text` produced a "plain-text" mail starting with the 100+
  lines of CSS embedded by `wrapEmailHtml()`.

- The client-access section (#172) now mirrors its HTML block into
  `textBody` using the same per-language strings, so plain-text
  recipients see the link / PIN / warning. `pinLabel = 'PIN'` moved
  into `clientAccessI18n` (RU uses ПИН-код).

- Added `getSupportEmail()` exported helper that reads
  `branding_support_email` from `app_settings` (JSON-decoded), with
  the SMTP from-address as fallback. Used by the gallery_expired and
  archive_complete callers below.

- Removed dead `require('handlebars')` (unused since the regex
  renderer landed; pre-existing lint error in this file).

Callers (data the templates already reference)

- `expirationChecker.js queueExpirationWarning`: send `expiry_date`
  (templates use this, the old code sent `expiration_date` —
  typo'd key, never read), drop the hard-coded `.de`/`en` sniff
  (the processor formats with the recipient's resolved language),
  add the `{{password_security_message}}` sentinel for
  `gallery_password` (plaintext is gone by warning time, so
  customers used to see literal `{{gallery_password}}` in the mail).

- `expirationChecker.js handleExpiredEvent`: both queueEmail calls
  now supply `host_name`, `event_date`, `expiry_date`,
  `support_email` so the EN/DE/NL/PT/RU `gallery_expired` template
  doesn't render literal `{{host_name}}, your gallery expired on
  {{expiry_date}}`. Skip the duplicate admin send when
  admin_email == customer_email.

- `archiveService.js`: `archive_complete` queue now supplies
  `host_name`, `photo_count` (from `photoEntries.length`),
  `archive_date`, `support_email` — the previous payload had only
  `event_name` and `archive_size`, so most of the mail was
  unfilled placeholders.

Tests

- `__tests__/services/emailProcessor.safeTemplateReplace.test.js`:
  16 cases — flat substitution, conditional truthy/falsy/missing/
  multi-line/sibling/numeric-0, plus 5 cases for the new
  `escapeHtml` option (default off, escape on, allowlist
  passthrough for welcome_message and gallery_link).

- `__tests__/services/emailProcessor.htmlToText.test.js`: 7 cases —
  the regression scenario (full wrapped body with embedded `<style>`
  block), tag-stripping, entity decoding, paragraph spacing.

- `__tests__/utils/formatters.test.js`: 12 cases for `escapeHtml`,
  `nl2br`, and the now-escaping `formatWelcomeMessage`.

35 cases total, all green. Lint clean on every touched file
(also fixes a pre-existing `no-prototype-builtins` warning in the
process). Pre-existing failures in
`__tests__/services/backupService.enhanced.test.js` are unrelated
and pre-date this branch.
