Settings: collapse advanced sections + dedicated About + default DB name

- DB default name: "proserve" → "proserveapi" (matches the ASTERION install
  script that provisions XAMPP on client machines).
- Settings dialog reorganized:
   1. License de mise à jour     [expanded] ← business-critical
   2. Langue                     [expanded] ← user preference
   3. ▸ PARAMÈTRES AVANCÉS       [collapsed by default]
        contains Server, Installation, Cache, Database, Logs
   4. À PROPOS                   [expanded] ← version + copyright
- The Expander hides plumbing the casual user shouldn't touch (server URL,
  install root, MySQL config, cache directory) but keeps it one click away
  for power users / support diagnostics.
- About card kept always-visible because version info is what support asks
  for first when troubleshooting.
