feat(call-log-detail): add realtime updates for analytics status

- Subscribe to call_logs table changes for the specific call log ID
- Auto-update UI when analytics status changes (pending → running → completed)
- Remove polling logic in favor of realtime updates
- Add live/offline indicator in detail page header
- Reuse existing realtime translations
