* fix(gateway): filter automated/noreply senders in email adapter Fixes #3453 Adds noreply/automated sender filtering to the email adapter. Drops emails from noreply, mailer-daemon, postmaster addresses and bulk mail headers (Auto-Submitted, Precedence, List-Unsubscribe) before dispatching. Prevents pairing codes and AI responses being sent to automated senders. * fix: remove redundant seen_uids add + trailing whitespace cleanup --------- Co-authored-by: devorun <130918800+devorun@users.noreply.github.com>
