fix: resolve startup issues with account activation, credit fetch and poll noise

- GoogleAPIService: try loadCodeAssist first for AI credits since
  fetchCredits returns 404 for many accounts; keep fetchCredits as
  fallback, removing the spurious warn on every poll cycle
- CloudAccountRepo: auto-activate the most-recently-used account when
  no account has is_active=1; downgrade noisy [DEBUG] log from info
  to debug level
- StatusBar: increase process-status refetch interval from 10s to 30s
  to reduce redundant IPC calls and log noise
