Release v1.0.1: installer locale detection from Step 1

User-facing improvements
- Installer detects browser language from the Accept-Language header
  on the very first request. de-* → Schneespur/DE, everything else
  (en-*, zh, ja, ar, it, fr, …) → Wintertrace/EN.
- DE/EN switcher in the installer layout header for manual override.
  The choice persists for the browser session.
- Step 5 (Config) now reflects the already-resolved locale instead of
  detecting again client-side, eliminating a brief "wrong language"
  flash between steps.

Under the hood
- New SetInstallerLocale middleware (Symfony's getPreferredLanguage
  with strict top-preference, list order ['en','de'] so non-matching
  browsers fall back to en/Wintertrace, not de/Schneespur).
- brand() helper resolves from the runtime locale when the app_brand
  setting is absent (pre-install). Post-install behaviour unchanged.
- Composer now declares ext-sodium explicitly (required by the Ed25519
  signature verification in the auto-update flow).

No DB migrations, no breaking changes, no config rewrites needed.
