feat(mail): default email_seed → \$PROJROOT/bait/ when unset

Browse Source 
When service_cfg["email_seed"] is absent, compose_fragment now falls
back to $PROJROOT/bait/ if that directory exists on the host. Lets
operators drop a deployment-wide bait corpus into one place without
threading email_seed through every decky's config. Missing dir keeps
old no-op behavior.
