The admin notification bell and dashboard "Recent Activities" panel were
showing raw snake_case keys ("event_published") or the generic
"Systemaktivität: <type>" fallback for ~65 activity types — most of them
from the CRM and Accounting modules added since #555. Users with German
locale saw the gap most visibly because the English placeholder leaked
through.
Three pieces:
1. notifications.service.ts — smart `default:` branch. Instead of falling
straight to the systemActivity template, derive the camelCase i18n key
from the snake_case type, try resolving `admin.notificationMessages.<camelCase>`
directly with the full metadata spread as params, and only drop to the
legacy template when no specific translation exists. This means every
future activity type just needs an i18n entry — no per-type switch
case to add.
2. en.json + de.json — added 65 missing `admin.notificationMessages.*`
bell entries and 58 missing `admin.activities.*` dashboard entries
across both locales. Covers Contracts (13), Quotes (7), Invoices /
Storno (12), Monthly billing (5), Expenses (4), Hours (5), Incoming
invoices (6), Customers (1), Admin user mgmt (3), and 9 misc /
legacy types (bulk_archive_completed, email_resent, email_queue_flushed,
email_template_created, event_duplicated, feedback_deleted,
feedback_moderated, feedback_settings_updated, word_filter_added).
Both locales finish symmetrical (149 activities / 136 notifications
each, vs. 91 / 71 before).
3. admin.service.ts `formatActivityMessage` messages dict — added the
same 58 English-only entries as a last-resort fallback for the
dashboard when i18n itself fails to load. Keeps the surface
resilient against bundle-load issues.
Metadata field names in the new translations match what the backend
writes via `logActivity()` — `{{contractNumber}}`, `{{quoteNumber}}`,
`{{invoiceNumber}}`, `{{username}}`, `{{template_key}}`,
`{{source_event_name}}`, `{{word}}` — verified against the call sites
in contractService, quoteService, invoiceService, userManagementService,
expenseService, adminEvents, adminEmail, adminFeedback.
DE wording authored natively; tone matches the existing terse,
maintainer-voice style of the rest of the file.
