Stop treating Provider.env length as credentials, refetch provider
sources after OAuth/API key writes, and respect an explicit auth-panel
Hide so OAuth-only providers do not stick on a stale "Credentials
missing" / empty-models state after a successful login.

Shows the auth panel only when provider credentials are actually required
Keeps custom providers defined in config from being treated as incomplete
Adds coverage for the new provider auth check
Only show the API key credential UI when a provider declares API auth
(or auth methods are still unknown). OAuth-only plugin providers such as
Cursor now show Connect/OAuth only, load auth methods on reconnect, and
skip an empty models section until models are discovered.
