fix(11): address code-review findings in catalog inline-edit

- WR-01: remove blur-commit on EditableCell toggle (onChange already saves+closes; prevents double updateServiceField)
- WR-02: skip server action when cell value unchanged (commit + new commitOnBlur dirty-check)
- WR-03: on blur, revert required-empty field via cancel() instead of leaving the cell stuck in error state
- WR-04: normalize it-IT price input (1.234,50) before parse; Number() rejects trailing garbage
- IN-01: render row error in its own <tr> instead of an invalid 7th <td> in a 6-column row
