Updating Jetcaster to only use dark color theme even when device isn't in dark mode

Summary of Changes

Hello @MagicalMeghan, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request simplifies the theming implementation for the Jetcaster Android application. It modifies the Theme.kt file to enforce a dark color theme across the entire application, overriding the device's system-wide dark mode setting and removing support for dynamic theming and light color schemes.

Highlights

• Forced Dark Theme: The Jetcaster application's theme logic has been updated to always apply the darkScheme, ensuring a consistent dark mode experience regardless of the device's system settings.
• Theme Simplification: All definitions and imports related to light color schemes, dynamic theming, and various contrast variations (medium and high contrast for both light and dark themes) have been removed, streamlining the theme configuration.
• Code Cleanup: The JetcasterTheme Composable function has been simplified by removing parameters for darkTheme and dynamicColor, as well as the conditional logic that previously selected between different color schemes.

Code Review

This pull request enforces a dark theme for the Jetcaster app by removing light theme support. The changes simplify the codebase by removing unused theme definitions. A critical issue regarding a breaking API change and medium-severity suggestions for further code cleanup have been identified.

[gemini-code-assist]

Removing the darkTheme and dynamicColor parameters from the JetcasterTheme composable is a breaking API change. Existing call sites providing arguments for these parameters will now cause compilation errors. Ensure all usages of JetcasterTheme are updated to the new signature.

Many of these imports are no longer used after the removal of light theme support. Removing unused imports keeps the code clean.

The colorScheme local variable is now redundant since the theme is always darkScheme. You can simplify the code by inlining darkScheme directly into the MaterialExpressiveTheme call.

    MaterialExpressiveTheme(
        colorScheme = darkScheme,
        motionScheme = MotionScheme.expressive(),
        shapes = JetcasterShapes,
        typography = JetcasterTypography,
        content = content,
    )
