Subject: [PATCH] Prepend email headers to message text passed to LLM

The LLM previously only received the stripped email body, giving it no
way to extract the sender's email address for the parentGuardian.email
field. Prepend Von:/Betreff: headers to every message so the LLM can
read the From address and subject without asking the parent for them.

The quoted_text sent back in the reply still uses only msg["body"] so
the quote block stays clean.
