Sprint 12+13: Tagebuch Day-One-Redesign, Notiz-Feature, Icon-Fixes, SW by-v405

Tagebuch:
- Day-One-Listenansicht: Wochentag + Tageszahl + Meta-Zeile (Zeit/Ort/Wetter)
- 4 Ansichten: Liste, Medien-Mosaik, Kalender (mit Sprungbuttons), Karte (GPS-Marker)
- Detail-Ansicht inline im Content-Bereich (kein Fullscreen-Overlay mehr)
- Hero-Bild vollständig sichtbar (object-fit:contain), Lightbox mit Safe-Area
- 2-Spalten-Layout Desktop: Text + Leaflet-Karte + POI-Liste
- EXIF-GPS-Extraktion bei Foto-Upload, historisches Wetter via Archive-API
- NoteStation-Import: Fotos in diary_media (80 Einträge migriert, 94 Medien)
- Stats-Endpoints: /diary/stats, /diary/calendar, /diary/locations

Notiz-Feature:
- Generische notes-Tabelle (parent_type + parent_id + meta_json)
- 📝-Button in 8 Bereichen, Notizblock-Seite mit KI-Analyse
- KI-Toggle in Einstellungen, notes_ki_enabled in User-Profil

Icons & Design:
- fill:currentColor Fix für welcome/onboarding/friends.js
- --c-icon Variable, --c-text-muted Dark Mode aufgehellt
- 15+ neue Phosphor-Icons aus lokaler Kopie
- CSS Network-First im SW, Cache-Control-Middleware

Infrastruktur:
- Wiki-Anreicherungs-Scheduler-Jobs entfernt (abgeschlossen)
- auth.py: notes_ki_enabled + is_social_media im User-Response
