chore: clean up migration files and update CLAUDE.md documentation

- Consolidate migration numbering (move full_bas_2026 to slot 044)
- Remove dead/superseded migrations (document_matching, reversal columns)
- Update CLAUDE.md with placeholder migration notes and corrected descriptions
- Fix migration SQL for invoice_inbox, extension_data, supplier_invoices
