Introduces a fully featured notification system with three delivery
channels (in-app, email, webhook), normalized per-user/per-event/
per-channel preferences, admin-scoped notifications, scheduled trip
reminders and version update alerts.
- New notificationService.send() as the single orchestration entry point
- In-app notifications with simple/boolean/navigate types and WebSocket push
- Per-user preference matrix with normalized notification_channel_preferences table
- Admin notification preferences stored globally in app_settings
- Migration 69 normalizes legacy notification_preferences table
- Scheduler hooks for daily trip reminders and version checks
- DevNotificationsPanel for testing in dev mode
- All new tests passing, covering dispatch, preferences, migration, boolean
responses, resilience, and full API integration (NSVC, NPREF, INOTIF,
MIGR, VNOTIF, NROUTE series)
- Previous tests passing
- toggleCompanyHoliday now calls loadStats() so the entitlement sidebar
updates immediately when a vacation day is converted to a company holiday
- deleteYear now deletes vacay_user_years rows for the removed year,
preventing stale entitlement data from persisting and re-appearing
when the year is re-created
- deleteYear recalculates carry-over for year+1 when year N is deleted,
using the new actual previous year as the source
- removeYear store action now calls loadStats() so the sidebar reflects
the recalculated carry-over without requiring a page refresh
- Add prev-year button (+[<] 2026 [>]+) so users can add years going
backwards after deleting a past year; add vacay.addPrevYear i18n key
to all 13 supported languages
