Replace Fragment-based UI with Jetpack Compose screens, adopting
Navigation3 for type-safe routing and Material3 theming throughout.

- Replace all Fragments/ViewHolders with Compose screens and cards
- Introduce NavigationController with Navigation3 runtime
- Add CapodTheme with Material3 design system
- Migrate PopUpWindow overlay to ComposeView with proper lifecycle
- Rewrite WidgetConfigurationActivity in Compose
- Add reusable settings composables (switch, slider, list preference)
- Update Kotlin to 2.2.10, add Compose BOM 2025.06.01
- Fix reactive state for unmatched devices toggle
- Add safety timeout for BT device enumeration
- Fix profile name validation error message
