Subject: [PATCH] feat: show build date/time on login screen across all apps
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add BUILD_TIME and BUILD_HASH exports to all version.ts files
- Add getBuildDefines() to all vite.config.ts for compile-time injection
- Add buildTime prop to shared LoginPage component
- Display formatted date/time next to version number (e.g. "v1.0.0 · 21.03.2026 10:30")
- Add app.d.ts type declarations for __BUILD_TIME__ and __BUILD_HASH__
