Implements GitHub issue #139 - allows users to create and manage custom
event types beyond the default presets (wedding, birthday, corporate, other).
Backend:
- Add event_types table migration with default system types
- Create eventTypeService for CRUD operations with legacy fallback
- Add adminEventTypes routes with full REST API
- Update event validation to use dynamic event types
- Update slug generation to use custom slug_prefix
Frontend:
- Add EventTypesPage with full CRUD admin interface
- Add eventTypes.service.ts API client
- Update CreateEventPage to fetch types dynamically
- Add Event Types navigation in admin sidebar
- Add i18n translations (EN/DE)
Backward compatible: existing galleries continue to work, legacy types
accepted even if database is empty via fallback mechanisms.
Fixed inconsistent storage path fallbacks that caused 500 errors when
serving thumbnails. The paths were using '../../storage' (2 levels up)
instead of '../../../storage' (3 levels up) when STORAGE_PATH env var
is not set.
