Fix key removal bug and remaining client vs serviceClient issues

Edge Function fixes:
- Fix two more places where 'client' was used instead of 'serviceClient'
  in runAgentGeneration (heartbeat update at line 1414, model info update at 1612)
- This fixes "Job Failed: Client Not found" error in production

Client-side fixes:
- settings.js: Use clearServerKey() function which handles device-specific
  AND legacy storage keys (was only removing legacy key)
- settings.js: Clear useBackgroundJobs setting on removal
- job-queue.js: clearServerKey() now also clears serverApiKey and sessionExpiresAt

Tests:
- Add 4 more tests for key removal edge cases:
  - Clear both device-specific and legacy keys
  - Clear useBackgroundJobs setting
  - Clear all session state (serverApiKey, sessionExpiresAt)
  - Verify key not visible after removal + page reload
