* feat: excuse one named account from the emailed login code, so a vendor reviewer who cannot read this instance's mail can sign in without turning codes off for everyone, with the reason recorded beside it and every run of warmblyctl status naming the accounts that hold one
* feat: create and manage tester accounts from the admin panel, so letting a reviewer in is a form rather than a shell, with the password shown once and every live exemption listed on one page because forgetting one is the way this goes wrong
* fix: give tester management its own permission bit rather than borrowing ban_users, create the account and its exemption in one transaction so no invisible orphan survives a failure, require an accountable operator on the CLI grant, stop a halted row scan reading as the whole exempt list, and show a failed query as an error instead of as no testers
* chore: re-run CI after the aggregator tripped on a cancelled job from the branch update, with every underlying job green
* chore: retrigger CI, the previous run sat queued indefinitely while other branches ran
* feat: roll back a half-created tester when its workspace step fails and backfill the manage-testers bit onto admins already holding every other permission, so the address is not left taken by an unusable account and the new routes are not 403 for the existing admin
* feat: make the 000151 manage-testers backfill one-way, because clearing bit 22 on the way down would also revoke it from an admin granted it explicitly afterwards and the up migration would not restore that
