feat(firewall): Inline-Note + Labels direkt in der Tabelle

- Migration 0035: note TEXT + labels TEXT[] für firewall_rules + nat_rules
- PATCH /firewall/rules/:id + /nat-rules/:id für note/labels Updates
- InlineNote: gold Tag mit MessageOutlined, Klick zum Bearbeiten (Enter/Blur speichert)
- InlineLabels: geekblue Tags mit X-Button zum Entfernen, "+" zum Hinzufügen
- Name-Spalte: Name + Labels + Note in Zeile 1, comment/auto-desc in Zeile 2
- Gleiche UX für NAT-Regeln
