Add per-event default photo sort setting with 6 options:
- Upload Date (Newest/Oldest First)
- Date Taken (Newest/Oldest First) — uses EXIF captured_at
- Filename (A-Z / Z-A)
Backend:
- Migration 077 adds default_photo_sort column to events table
- Event create/update handlers accept and validate the setting
- Gallery info endpoint returns default_photo_sort for frontend
Frontend:
- "Date Taken" added to gallery sort dropdown (alongside Date, Name,
Size, Rating)
- Gallery initializes with event's default sort instead of hardcoded
"date"
- "Default Photo Sort" dropdown in event create and edit forms
- Photos without EXIF dates fall back to upload date
i18n: All 5 locales (EN, DE, NL, PT, RU) updated with sort labels.
