feat(tickets): Rückfragen-Dialog, Verlinkungen, Entwurfssicherung + PWA-Vorbereitung

- Feedback: fixNote (Changelog), agentContext (intern), thread (Q&A-Verlauf);
  3 gefilterte Ansichten (Rückfragen/Offen/Geschlossen)
- Tickets-Text: klickbare Tier-Links (ID→Name), Ticket→Ticket-Links (?focus=),
  Markdown-Links; Antwort-Entwurf pro Ticket in localStorage
- "Fehler melden": Entwurf übersteht App-Wechsel/Schließen (ein gemeinsamer Entwurf)
- entityName als Hyperlink zum referenzierten Datensatz
