- send_irp_submission now REQUIRES and ATTACHES the signed Power of Attorney PDF
(downloaded from MinIO) — the state won't act on a third-party filing without
it, and 'on file, available on request' stalls the request. If the POA isn't
available we don't email and fall back to a manual todo.
- Backfill missing legal_name + registered address from the FMCSA census so the
submission isn't sent with a blank address (root cause of the empty
'Legal/registered address: , ,' line). Customer-supplied values win.
- state_trucking passes signed_auth_key through to the IRP submitter.
- Fix 'Object of type date is not JSON serializable' when creating the admin
todo (json.dumps(..., default=str)) — broke the intrastate (bash-fee) path.
