fix(email): accept forwarded emails regardless of original sender

Gmail preserves the original sender when forwarding — whitelist check
was blocking all Fwd: emails not from mmarius28@gmail.com.
echo@romfast.ro is private, so any Fwd: arriving there is from Marius.
Also strip ***SPAM*** prefix from slugs for cleaner filenames.
