refactor: rename Audio Room → Nest project-wide

Aligns class names, package paths, string resource keys, UI text and
intent actions with the Nests branding used by the EGG specs in
nestsClient/specs/. Mechanical rename — no behavior change.

- Folders: audiorooms/ → nests/ (5 paths across amethyst, quartz)
- 30+ class renames (AudioRoom* → Nest*, AudioRooms* → Nests*)
- String resource keys audio_room_* → nest_*
- UI strings "Audio Room"/"Audio Rooms" → "Nest"/"Nests" (incl. all locales)
- Intent extras AUDIO_ROOM_* → NEST_*
- Compose route Route.AudioRooms → Route.Nests

Spec-aligned identifiers (MeetingSpaceEvent, meetingSpaces/, the nip53*
packages) are intentionally untouched — those are NIP-53 protocol
names, not "audio room" branding.
