Confirm before sending; add address + contact to job offers

"Bewerbung senden" now asks for an extra confirmation (with the
recipient) before dispatching.

Job offers gain adresse and ansprechpartner fields — shown, editable,
and carried through the REST API upsert (Swagger updated). Taking an
offer over now writes the employer address (street, number, city) and
the contact person into the application's AI notes (llm_notizen), so the
LLM can use them for the letter's Anschriftfeld and salutation.
