openapi: remove unused hub profile endpoints

GET /api/hub/profiles/{username} (getHubProfile) and PUT /api/hub/profiles/me
(updateMyHubProfile) have no implementation in core and no callers in any
Comfy-Org client (verified org-wide). Removing both from the shared spec.
GET /api/hub/profiles/me is retained — it's actively used by the frontend.
