Add 1-click PDF export for tickets (craftsman handoff)

Implements the "1-Klick-PDF-Export für Handwerker" requirement from the ticketing module spec, which existed only as a schema stub (HandoverProtocol.pdfUrl) with no actual generator anywhere in the codebase. Adds a server-side PDF endpoint (pdfkit, no headless browser needed) summarizing a ticket's category, priority, status, room, reporter and description, plus a "PDF" button in the landlord cockpit that downloads it via an authenticated blob fetch (the API uses a Bearer token, not cookies, so a plain <a href> wouldn't carry auth).
