UI: Add features for player controls, lyrics notifications, and widgets

[SteveZMTstudios]

Summary

• Card widget — a new responsive home-screen widget family for quick playback control. One provider delivers pill (1×1), circle (2×2 w/ progress ring), card (4×1), medium (4×2) and large (4×4 / wide 5×4) layouts, plus favorite & shuffle actions on wide slots.
• Notification lyrics — opt-in setting that surfaces the current synced lyric line in both the expanded media notification and the system media session metadata (lockscreen / BT / Android Auto), with the original title+artist preserved as the subtitle line.
• Swipe cover to switch track on the full player (default enabled); gesture recognition keeps vertical gestures & single-tap behavior intact.
• Optional rotating cookie play/pause button to match the cover-rotation feel while playing, controlled by a player setting.
• "Always skip to previous track" behavior — opt-in flag so pressing Previous jumps straight to the last item instead of seeking back to track start, useful for heads-free and hardware-button use cases.
• Widget favorite action connects through a dedicated playback-service helper so the current item's heart rating and widget state stay in sync across lyric/session updates.
• Widget resources use Material You system colors on Android 12+ with stable theme-token fallbacks for pre-12 and night mode; default + zh-rCN strings added for all new settings and the widget picker label.

Hi, thank you very much for your PR.

To make review easier, please can you split features to have one PR per feature?

[nift4]

Please make sure the individual branches are buildable, some currently aren't. Thanks

[SteveZMTstudios]

[SteveZMTstudios]

done.
Although all four branches can be compiled, due to capacity constraints, I only conducted a rigorous test on this comprehensive branch.

If you feel something is out of place, please point it out here. If you are satisfied with these changes, it is a good idea to merge this pull request but not others to avoid possible conflicts.

Thanks, I will take a look when I have some time.

I am testing tested this change on my device chain to ensure the low_end device performance and old Android sdk compatibility.
