This commit introduces several enhancements to the SnackBar functionality within the design system:

- Refactors `SnackBarController` and introduces `SnackBarData` for better state management and customization of SnackBar messages, types, and durations.
- Implements `SnackBarControllerImpl` to handle the display logic and queuing of SnackBar messages using coroutines.
- Adds `SnackBarState` to manage the visibility and data of the SnackBar.
- Introduces `SnackbarDuration` enum to define standard display times for SnackBars (Short, Medium, Extensive, Indefinite).
- Defines default icons for `Success` and `Error` `SnackBarType`s.
- Updates `ScaffoldWithSnackBar` to use the new `SnackBarControllerImpl` and `SnackBarData`, and collects state using `collectAsStateWithLifecycle`.
- Introduces `SnackBarAnimationConfig` to allow customization of SnackBar enter and exit animations and duration.
- Renames `CustomSnackBarUI` to `DefaultSnackBar` for clarity.
- Simplifies icon handling in `DefaultSnackBar` by using `data.snackBarType.getDefaultIcon().painter`.

This commit updates the SnackBar implementation across the app.

- Replaced `showMessage` with `showSnackBar` and wrapped parameters in `SnackBarData` class for better organization in `ViewItemsScreen.kt`, `BookmarkSheet.kt`, and `ListScreen.kt`.
- Renamed `CustomSnackBarUI` to `DefaultSnackBar` in `NavHostGraph.kt`.
- Simplified `rememberSnackBarController()` in `LocalSnackbarController.kt`.

This commit refactors the error handling in the Login screen.
- Removes the `SnackBarAnimation` composable and replaces it with the `SnackBarController` from the design system to display error messages.
- Updates `LoginViewModel` to set a generic `ErrorState.RequestFailed` without a specific message, as the message is now handled by the UI.

This commit refactors the snackbar visibility logic in `ScaffoldWithSnackBar.kt` and `SnackBarControllerImpl.kt`.

In `ScaffoldWithSnackBar.kt`:
- The `AnimatedVisibility` composable now wraps the `snackBar(data)` call directly.
- The null check for `currentSnackbarData.data` is now performed inside the `AnimatedVisibility` content.

In `SnackBarControllerImpl.kt`:
- The `processNextMessage` function now uses a `queueMutex` to safely remove the next message from the `messageQueue`. This prevents potential race conditions when accessing the queue.
- If the queue is empty, the coroutine launched to process the message will now return early.

This commit refactors the `MovieDetailsScreen` to use the `rememberSnackBarController` and `SnackBarData` from the design system for displaying success and failure messages for ratings. This replaces the previous `SnackBarAnimation` composable.

Key changes:
- Integrated `rememberSnackBarController` to manage SnackBar display.
- Used `SnackBarData` with `SnackBarType.Success` and `SnackBarType.Error` for rating feedback.
- Removed the custom `SnackBarAnimation` composable.
- Utilized the `.string` extension function for cleaner string resource access.

This commit updates the rating success/failure snackbar in `EpisodeDetailScreen.kt` to use the `SnackBarController` and `SnackBarData` from the design system, replacing the custom `SnackBarAnimation`.

This change standardizes the snackbar implementation and leverages the design system's snackbar types (Success/Error).

This commit replaces the custom `SnackBarAnimation` with the `rememberSnackBarController` and `SnackBarData` from the design system for displaying success and failure messages for ratings.

- Updated `TvShowDetailScreen.kt` to use `rememberSnackBarController` to manage SnackBar display.
- Replaced `SnackBarAnimation` calls with `snackBarController.showSnackBar()` using `SnackBarData`.
- Set `SnackBarType.Error` for both success and failure messages, which seems like a potential bug that might need further attention.

This commit removes the `SnackBarAnimation.kt` file as it is no longer needed. The functionality provided by this composable can be achieved using the snackBarController

This commit updates the `AppNavBar` composable:
- Simplifies screen width calculation by directly using `LocalConfiguration.current.screenWidthDp.dp`.

This commit renames the `SnackbarDuration.Short` enum value to `SnackbarDuration.Brief` in `SnackBarController.kt`. The corresponding millisecond value remains unchanged at 1500.
