- AudioInputSection now subscribes to AudioManager.onResumed and bumps an
audioCtxGen state on each 'running' transition. Mic-level meter and
resolved-default hint effects depend on it, so opening Settings before
joining voice and then joining voice activates the meter without needing
to remount the panel. Footer copy updated to match the new behavior.
- SectionShell and DropdownItem extracted to
settingsPanels/_shared/SettingsPickerPrimitives.tsx so Task 6
(AudioOutputSection) can import them instead of triplicating the markup.
The _shared/ folder keeps these settings-internal primitives out of the
broader ui/ namespace.
- Deliberate scope choice: VideoSection.tsx still has its own DropdownItem
copy. Unifying all three is left to a follow-up; touching VideoSection
here would expand scope beyond the audio-device-ux branch.
