1.5.1

- Due date uses days selector in edit mode (same as create)
- Overdue invoices fully editable (same as issued)
- Overdue status reversed to issued when due date moved to future
- Invoice list: edit icon for issued/overdue, eye for paid
- Invoice list: PDF opens blob from NAS (removed lang modal)
- NAS cleanup: properly scans directories when cleaning old PDFs
- Fixed syntax error from leftover else block
