Clamp quick settings page math to valid bounds and guard volume OSD\ncontrols when PulseAudio objects are absent. Remove unused delegate\nrequired properties tied to enabled state.
Apply Motion tokens to notification drag and stack transitions, volume OSD feedback, KRunner field state, media controls height changes, and action-button popup affordances. Leave timeout and marquee animations as timing behavior.
This commit makes a much needed cleanup and overhaul of the volume OSD.
Changes:
- Fix context menus for app streams
- Remove dedicated mute button in cards (simplifies the UI for touch
devices)
- Add selection background for card delegates
- Sync audio models with plasma-pa
- Simplify implementation of cards
- Sync volume slider implementation with plasma-pa
