## Summary
- Budget periods use `date` columns (`start_date`, `end_date`) but
queries compared them against `now()` which includes a time component
(e.g. `2026-01-31 15:30:00`). MySQL converts the date to midnight for
comparison, so `end_date >= now()` evaluates to `'2026-01-31 00:00:00'
>= '2026-01-31 15:30:00'` → **false** — causing "No active period" on
the last day of every period.
- Replaced `now()` with `today()` (date-only) in all budget period date
comparisons across `Budget::getCurrentPeriod()`,
`BudgetController::index()`, and `GenerateBudgetPeriods` command.
## Test plan
- [x] Added 4 Pest tests covering the edge case (last day at various
times, first day at end of day, index/show endpoints)
- [x] All existing budget tests pass
