Capture : viewfinder=0 avant prise (AF phase-détection), timeout 20s, spinner UI

- camera.py : désactiver LiveView avant capture (viewfinder=0) → miroir abaissé →
  AF phase-détection Canon actif. Remplace _declencher_af_liveview (autofocusdrive=1
  pouvait bloquer sur certains corps Canon). activer_viewfinder() après la prise.
- main.py : fix bug global _preview_actif dans api_capturer (était variable locale,
  le global restait True). Timeout asyncio 20s sur run_in_executor pour éviter freeze
  permanent si capture bloque. Logs INFO avant/après capture.
- camera.js + index.html + style.css : spinner "Capture en cours..." entre le flash
  et l'affichage du résultat. Cacher le spinner dans afficherErreurCapture aussi.
