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
