Kyle Pope 46d4c5e28b Implement todo recurrence logic with auto-reset scheduling
Backend:
- Add reset_at (datetime) and next_due_date (date) columns to todos
- Toggle endpoint calculates reset schedule when completing recurring todos:
  daily resets next day, weekly resets start of next week (respects
  first_day_of_week setting), monthly resets 1st of next month
- GET /todos auto-reactivates recurring todos whose reset_at has passed,
  updating due_date to next_due_date and clearing completion state
- Alembic migration 014

Frontend:
- Add reset_at and next_due_date to Todo type
- TodoItem shows recurrence badge (Daily/Weekly/Monthly) in purple
- Completed recurring todos display reset info:
  "Resets Mon 02/03/26 · Next due 06/03/26"
