Backend: galerie session /s/{code} + upload API

Browse Source 
Ajoute deux routes FastAPI :
- GET /s/{code} → galerie HTML mobile avec auto-refresh 15s
- POST /api/sessions/{code}/upload → stockage photo dans session_{code}/

Corrige layout admin : titre sm au lieu de lg, compteur sans chevauchement.
Wizard step 2 : code affiché en lg (96px) au lieu de xxl (300px).
