feat: fondations E2E + 2 bugs trouvés (onglets ?view=, Inter CSP) (v7.36.0)

Ajout — e2e/smoke.spec.js (2 gates verts contre l'instance de test) :
- gate A39 : bascule de vues d'une collection (clic onglet Calendar →
  ?view_type=calendar, grille .calendar + .cal-header rendue ; collection
  créée puis SUPPRIMÉE = répétable)
- gate A20 : palette Ctrl+K (ouverture Alpine .open, recherche GET rend
  .cmd-palette-item, fermeture Échap)
- filet console : 0 erreur JS/CSP (bruit Failed to load resource 401/403
  filtré)
- Service Workers bloqués : /sw.js sert sa page « hors ligne » sur les
  navigations redirigées (redirect:'manual') — pwa_offline.spec.js couvre
  le SW
- bootstrap autonome : login OU création du compte e2e documenté (jamais
  de mot de passe deviné), workspace si absent
- commande : cd e2e && node node_modules/@playwright/test/cli.js test smoke.spec.js

Fixed — trouvés par les gates :
1. Bascule de vues standalone JAMAIS fonctionnelle : les onglets
   émettaient ?view=… mais la route lit `view_type` (FastAPI) → l'onglet
   restait sur Table quel que soit le clic (bug pré-existant, A28 n'y est
   pour rien). Onglets → ?view_type= ; test_all_view_tabs_present adapté +
   assertion comportementale (GET ?view_type=calendar rend .calendar).
2. Inter bloqué par la CSP depuis v7.27 : app.css importait encore
   Google Fonts (@import raté par le grep de la passe v7.27) → violation
   style-src sur chaque page + police en fallback. Inter auto-hébergé :
   2 faces variables (100-900, latin + latin-ext) dans static/fonts/,
   @import supprimé (8 fichiers dupliqués dédupliqués → 2).
