Refresh the Flutter snapshot: UI-01 through UI-09, plus a fresh installable APK

Full UI redesign pass complete: persistent tab shell with an always-visible
background map, Modern Professional Dark theme, monochrome dark map tiles,
offline skeleton map, a shared GlassPanel/FloatingPill component kit,
customizable HUD telemetry widgets, and the Map HUD / Plan & Route Planning /
Rides History screen rebuilds. 374 tests passing, up from 316.

The APK is a fresh release build (debug-signed, no release signing config
exists yet).
