Add GET /auth/api/check endpoint for unauthenticated user permission checks

Checks permissions for a user given by ?user=<UUID> query arg without
requiring a session cookie. No cookie is read or written, no DB writes.

- perm= query arg supported (same wildcard semantics as validate/forward)
- Returns valid bool + minimal ctx (user/org/role/permissions)
- Permissions are host-scoped via domain filtering, same as session_ctx
- 404 if UUID not found; valid=false if perm check fails (no 403)
- Add ApiCheckUserResponse struct to apistructs
- Add has_all_scopes() helper to permutil for scope-set-based checks
