Replace printed/unprinted tabs with unified list and inline filters

- All checks shown in one table by default (load all, no server-side printed filter)
- Add payee search, date-from/to, and status filter controls to toolbar
- Filtering is client-side; no extra API calls on filter changes
- All checks get Edit/Delete buttons regardless of printed status
- All checks get checkboxes for PDF selection
- Remove separate Reprint button and reprintCheck function
- Remove printed guard from PUT and DELETE endpoints
