Bug/customer cron job (#516)

* fix(reminder-processor): filter out credited invoices in overdue reminders

* feat: implement linking of transactions to journal entries

- Added POST endpoint for linking a bank transaction to an existing journal entry without creating new bookkeeping.
- Implemented validation for required fields and error handling for various scenarios (e.g., missing journal_entry_id, transaction already linked, journal entry not found).
- Created tests for the new endpoint to cover various cases including successful linking, error responses, and invoice handling.
- Introduced duplicate payment detection logic to prevent double-booking of bank receipts.
- Added a new component for correction affordance in the UI to facilitate user corrections on journal entries.

* feat(invoice-matching): enhance force matching with expected journal entry validation
