Why: independent review flagged the issue client still targeting the 410
endpoint and a hint sentence ending with a period.
Evidence: npm run build + npm test re-run on the fix (SELF).
Impact: api client surface only.
Refs: review brief /tmp/review-brief-admin-user-contract.md
Why: backend 8dfc223 replaced POST /api/admin/users with strict
{owner, profile} decoding and returned 410 for login-key issuing, so the
UI create form failed with 400 unknown field name. Creation now sends
{owner, profile:{name}} only; password input, admin checkbox and the
login-key issue entry are removed; notice points to the local CLI
initialize-account flow. passwords.ts lost its only consumer.
Evidence: npm run build + npm test (34 files/293 passed) + knip identical
to baseline on the task worktree (SELF).
Impact: UsersPanel and api client only; no style/token changes.
