feat: enhance supplier invoices, entity-aware categorization, and new tests

Expand supplier invoice module with overdue cron job, credit note journal
entries, and event emissions on approve/mark-paid/create flows. Add entity
type (EF/AB) awareness to transaction categorization UI and category
mapping logic. Add comprehensive tests for supplier-invoice-entries,
transaction-entries, and expanded API route coverage.
