Release 1.5.0

• PR #309 - Add weekly and annual scheduled transaction types
  • Weekly (Day of Week): Transactions that recur every week on a specified day (e.g., every Monday). Weekly transactions appear twice per pay period since each weekday occurs exactly twice in a 14-day biweekly period.
  • Annual: Transactions that recur on a specific month and day each year (e.g., April 15th). For February 29th, the transaction is skipped in non-leap years.
  • Database migration adds day_of_week, annual_month, annual_day columns to scheduled_transactions table
  • Updated frontend modal with day-of-week dropdown and month/day inputs for new transaction types
  • Added type filter options for weekly and annual transactions
