Refactor to eliminate keyboard/mouse handler disconnects

Extract duplicate logic into shared action functions to ensure
consistent behavior between keyboard and mouse interactions:

- action_remove_from_playlist: Unified playlist removal logic
- action_play_from_playlist: Unified playlist playback with optional
  pause state preservation
- handle_context_menu_action: Unified context menu execution

Fixes:
- Remove from playlist now checks index before removal (was broken
  in keyboard 'd' handler)
- Mouse double-click on playlist now preserves pause state
- Context menu handling no longer duplicated across 400+ lines

All keyboard and mouse actions now use identical code paths,
eliminating state bugs from inconsistent implementations.
