Root cause of recurring 'Password not found for Email Account Performance West
Outgoing': the account was shipped as a fixture with awaiting_password=1 and no
password. Email Account SMTP passwords are encrypted per-site and cannot live in
a fixture, so every `bench migrate` reimported the fixture and re-broke
outgoing mail (login notifications, password resets, welcome emails).
- Remove the Email Account fixture (it cannot carry the encrypted secret).
- Add email_account_sync.sync_outgoing_password: idempotent, exception-safe
upsert that reconciles the account + password from SMTP_* env and clears
awaiting_password.
- Wire it to after_migrate (repairs at end of every deploy/migrate, right after
fixtures import) and the daily scheduler (heals out-of-band restore/restart
drift).
- Pass SMTP_* into the erpnext + erpnext-scheduler containers so the sync has
the secret (they previously had no SMTP env).
