Add opt-in office sound cues

[iamlukethedev]

Summary

• Add per-gateway officeSound Studio settings with enable/volume controls.
• Add Studio Settings controls for office sound cues.
• Add a small Web Audio cue engine for task start, task complete, alarm, doorbell, and chime cues.
• Wire run lifecycle and external office events into opt-in office sound playback.
• Add unit coverage for sound settings normalization/merge and cue resolution.

Testing

• npm run test -- --run tests/unit/officeSound.test.ts tests/unit/studioSettings.test.ts tests/unit/officeEventsRoute.test.ts tests/unit/operationsCenterPanel.test.ts tests/unit/stateAnimationMappingsEditor.test.tsx tests/unit/officeEventTriggers.test.ts
• npm run typecheck
• npm run smoke:dev-server
• Browser walkthrough: opened Studio Settings, enabled Office sound cues, adjusted volume, and verified persisted officeSound settings via /api/studio. Note: the dev browser session also shows the existing white-canvas/background issue while opening settings; the sound controls render and persist.
