Initial Work for Settings Page with Jetpack Compose

- Implemented a new settings page using Jetpack Compose.
- Added a new settings option to enable the redesigned settings page.
- This option allows for gradual integration and testing of the new
  settings page, minimizing disruptions to current functionality.

Plan for Settings Items:
- Jetpack Compose does not have a direct equivalent to the
  Preference/settings library.
- We could consider using third-party libraries that offer preference
  items as composables.
- However, these libraries may be incomplete or lack active development.
- Given our specific needs for only a subset of preference types,
  creating custom composables would be beneficial.
- This approach allows for fine-tuning the components to our specific
  use case.

Next Steps:
- Continue development by adding more composables for settings
  functionalities and screens.
