Subject: [PATCH] Task #10: Send automatic confirmation email to contact form
 submitters
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After a visitor submits the contact form, Brevo now sends two emails:
1. The existing notification to jh@unixweb.de with the message details
2. A new confirmation email to the sender's address

The confirmation email:
- Is sent from "Joachim Hummel <jh@unixweb.de>"
- Addresses the sender by name
- Thanks them and sets response-time expectations (1-2 Werktage)
- Includes both plain-text and HTML versions
- Is logged separately via req.log.info for observability

If either email fails, the entire request returns a 500 error (atomic
behavior — both succeed or neither does from the user's perspective).

File changed:
- artifacts/api-server/src/routes/contact.ts

Also ran `pnpm --filter @workspace/api-spec run codegen` to fix a
pre-existing typecheck failure caused by stale generated lib output.
Typecheck passes cleanly after codegen.
