Separate exclude and one-time transaction handling (#2400)

* Separate exclude and one-time transaction handling

- Split transaction "exclude" and "one-time" toggles into separate controls in transaction detail view
- Updated Transaction::Search to show excluded transactions with grayed-out styling instead of filtering them out
- Modified IncomeStatement calculations to exclude both excluded and one_time transactions from totals
- Added migration to convert existing excluded transactions to also be one_time for backward compatibility
- Updated transaction list view to show asterisk for one_time transactions and gray out excluded ones
- Added controller support for kind parameter in transaction updates
