* fix: bind job-read override fast-path to permissioned_as_email
Replaces the reserved-label / label-* exclusion approach: webhook-/http-/email-
labels are created through the public token API by the trigger panels, so they
cannot be reserved, and blocking label-* regressed legitimate re-reads. Instead
the username_override fast-path now requires the job's permissioned_as_email
(non-forgeable, never derived from the label) to equal the caller's email.
