The Email Worker rejects mail from senders that are not in the user's
approved-sender allowlist. With an empty allowlist the very first send
("email it to yourself") bounces with an approval-pending notice, which
is the wrong first impression for the feature.
Seed the caller's verified account email as `approved` the moment we
lazily create the user's send_addresses row. Best-effort: address
creation still succeeds if the seed insert fails (idempotent via the
existing UNIQUE (user_id, email) constraint).
