Improve routine configuration: delete triggers, fix pause, add feedback

- Add trash icon button to delete triggers (full stack: service, route, API client, UI)
- Fix pause/unpause bug where saving routine could revert status by excluding
  status from the save payload (status is managed via dedicated pause/resume buttons)
- Add toast feedback for run, pause, and resume actions
- Auto-switch to Runs tab after triggering a manual run
- Add live update invalidation for routine/trigger/run activity events
