This pull request integrates Jetpack Compose into NewPipe by:
- Adding the necessary dependencies and setup.
- This is part of the NewPipe rewrite and fulfils the requirement for
  the planned settings page redesign.
- Introducing a Toolbar composable with theming that aligns with
  NewPipe's design.

Note:
- Theme colors are generated using the Material Theme builder (https://m3.material.io/styles/color/overview).
