Critical fixes:
- [C1] _reactivate_recurring_todos now uses flush + with_for_update
instead of mid-request commit; get_todos commits the full transaction
- [C2] recurrence_rule validated via Literal["daily","weekly","monthly"]
in Pydantic schemas (rejects invalid values with 422)
Warnings fixed:
- [W3] Clear due_time when due_date is set to null in update endpoint
Suggestions applied:
- [S2] Wrap filteredTodos in useMemo for consistent memoization
- [S6] Add aria-labels to edit/delete icon buttons

When editing an already-completed todo to add/change recurrence or
due_date, recalculate reset_at and next_due_date so the reset info
displays immediately without needing to uncomplete and re-complete.

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"
