M7: REST-Transport erstmals live verifiziert, vier Bugs gefunden+gefixt
Erstmaliger REST-Schreibtest gegen echte Hardware (www-ssl vorher auf jedem Testgerät aus, Pfad lief nur gegen Mocks). Vier Bugs gefunden: - baseURL fehlte trailing slash, relative URL-Auflösung warf "/rest" aus jedem Pfad (404, fiel still auf SSH zurück statt Zertifikat- Dialog zu zeigen) - .add nutzte POST statt PUT (RouterOS' REST-API erwartet PUT für neue Einträge) - RouterOS sendet Cache-Control: max-age=31536000 auf jede REST- Antwort, URLSession cachte dadurch die erste (leere) GET-Antwort für den Rest der App-Laufzeit - Löschen aktualisierte die Experte-Tab-Liste nicht in-place (SwiftUI- Render-Problem, kein Datenfehler) — Anlegen/Bearbeiten laufen über ein Sheet, dessen Schließen automatisch neu rendert, Löschen über ein confirmationDialog ohne Remount Anlegen/Bearbeiten (inkl. Feld-Leeren)/Löschen live bestätigt. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
