fix(aap): Fix stem actions volume control, reset button, and Default/No Action semantics

Fix volume up/down doing nothing by using adjustSuggestedStreamVolume instead of dispatchMediaKeyEvent which ignores volume keycodes. Add reset-to-defaults button with confirmation dialog in the stem actions TopAppBar. Rename 'None' to 'Default' (firmware handles the press) and add 'No Action' (claimed but do nothing) to correctly model per-press-type claim mask semantics. Remove disableNone lock; add cross-side auto-set logic so selecting Default resets both sides and selecting an action promotes the other side from Default to No Action.
