feat: Support per-dispensary schedules (not just per-state)

- Add dispensary_id column to task_schedules table
- Update scheduler to handle single-dispensary schedules
- Update run-now endpoint to handle single-dispensary schedules
- Update frontend modal to pass dispensary_id when 1 store selected
- Fix existing "Deeply Rooted Hourly" schedule with dispensary_id=112

Now when you select ONE store and check "Make recurring", it creates
a schedule that runs for that specific store every interval.
