Fix: Resolve critical build and runtime errors

This commit addresses a series of cascading errors that prevented the Android client from compiling and running correctly.

Build & Configuration:
- Corrected the `namespace` in `build.gradle` to match the project's package structure, resolving all `Unresolved reference: R` and data binding errors.
- Wrapped layouts (`activity_connect`, `servers_fragment`, etc.) in `<layout>` tags to enable data binding class generation.

View Logic & Rendering:
- Updated `onScroll`/`onFling` signatures in `WorkspaceView` to handle nullable MotionEvent parameters.
- Fixed a Kotlin smart cast error in `ServerDetailsFragment` by caching a mutable property in a local variable before use.
- Replaced a direct call to an internal color in `ServerDetailsAdapter` with a safer, theme-aware attribute lookup using `MaterialColors`.
