v1.1.1: Fix server reconnection, sync progress, and seed phrase handling

- Fix UI stuck on "Reconnecting" after server switch: HomeViewModel now
  rebinds flows to the new synchronizer via syncRestarted signal
- Show live sync progress during download/scan phases using weighted
  totalProgress (40% download + 60% scan) with block heights
- Handle DEADLINE_EXCEEDED errors the same as UNAVAILABLE (show server picker)
- Fix seed phrase validation: normalize input to lowercase, prefer exact
  word matches over autocomplete
- Wrap server picker reconnection in try/catch to prevent crashes
- Preserve birthday height when resetting synchronizer for server switch
- Run findReachableServer on IO dispatcher to avoid blocking main thread
- Guard Twig debug logging behind BuildConfig.DEBUG
- Add build.sh script for debug/release builds
- Bump version to 1.1.1, SDK to 1.9.1-beta01
