This commit adds a new "About" screen to the application, accessible from the Settings screen.

The "About" screen displays:
- The application's icon and version number.
- A brief description of the application.
- A biography of the developer, TheVeloper.
- An acknowledgements section with clickable links to GitHub and Telegram profiles.

This commit also fixes a crash that occurred when opening the "About" screen. The crash was caused by an `IllegalArgumentException` when trying to load an adaptive icon XML as a painter resource. The fix is to load the icon from the `assets` folder as a bitmap, which avoids the resource resolution issue.

This commit also fixes a crash that occurred when opening the "About" screen. The crash was caused by an `IllegalArgumentException` when trying to load an adaptive icon XML as a painter resource. The fix is to use the monochrome icon from the drawables folder, as requested by the user.

This commit updates the app icon displayed on the `AboutScreen`.

The key changes are:
- The app icon resource is changed from `R.drawable.monochrome` to `R.drawable.new_monochrome`.
- The size of the icon is increased from `128.dp` to `228.dp`.
- A `colorFilter` is applied to tint the icon with the primary color of the current MaterialTheme.

This commit completely refactors the AboutScreen to align with a more modern, Material 3 expressive design and to improve its functionality.

The following changes have been made:
- Implemented a collapsing top bar, mirroring the behavior of the SettingsScreen.
- Made the entire screen content scrollable within a `LazyColumn`.
- Replaced the previous static biography with a generic greeting message, thanking the user for using the app.
- Redesigned the contributor cards using `Surface` and `AbsoluteSmoothCornerShape` for a more expressive, modern look.
- Ensured the main bottom navigation bar is hidden when viewing the AboutScreen.

This commit completely refactors the AboutScreen to align with a more modern, Material 3 expressive design and to improve its functionality. It also fixes a compilation error related to the screen's entry animation.

The following changes have been made:
- Implemented a collapsing top bar, mirroring the behavior of the SettingsScreen, with a fully scrollable `LazyColumn`.
- Replaced the previous static biography with a generic greeting message, thanking the user for using the app.
- Redesigned the contributor cards using `Surface` and `AbsoluteSmoothCornerShape` for a more expressive, modern look.
- Ensured the main bottom navigation bar is hidden when viewing the AboutScreen.
- Fixed a `TypeMismatch` error by using `MutableTransitionState` instead of `MutableState` for the entry animation, ensuring the screen compiles and animates correctly.

This commit introduces several improvements to the `AboutScreen`:
- A new app icon (`new_monochrome`) is used and tinted with the primary color.
- The version name is displayed in a styled `Box` with a tertiary container background.
- GitHub and Telegram icons have been added for the contributor section. Clicking these icons opens the respective profile URLs.
- The Telegram support URL has been updated.

Additionally, the following changes were made:
- In `LibraryScreen.kt`, the `mvContainerColor` and `mvContentColor` in `EnhancedSongListItem` now use primary container colors for better consistency when a song is current and not loading. The favorite songs list now uses `EnhancedSongListItem`.
- The `AboutScreen` has been added to the list of routes where the navigation bar should be hidden in `MainActivity.kt`.
- New vector drawables for GitHub (`github.xml`) and Telegram (`telegram.xml`) icons have been added.
