Verified against the Echo routes and handler structs, fixing drift that
would break API clients:
- login: response field is access_token, not token (AuthResponse struct)
- register status: status is only pending|approved; expiry is HTTP 410
(not a status value), approved responses are single-use, and pending
registrations do not survive server restarts
- visible libraries: endpoint is GET /api/libraries/visibility and
returns a top-level array of full library rows, not a wrapped object
- media items list: response is {"data": [...]}, library_id is optional,
limit defaults to 50 (max 1000), no total field; document the sort
parameter, the two response shapes, and raw-vs-resolved file paths
refresh and device-registration docs verified accurate; no changes.
