chore: remove unused loadRefreshToken and loadAccessToken stubs

[detail-app]

Removed the loadRefreshToken(OAuthClientInformation, String) and
loadAccessToken(String) declarations from the
OAuthAuthorizationServerProvider interface, their @Override
implementations in UserSSOOAuthProvider, and the now-unused
org.openmetadata.mcp.auth.AccessToken import.

These were dead code: both overrides threw UnsupportedOperationException
(comments stated "not used in the current implementation") and had zero
production callers and zero test callers. The interface is internal to
OpenMetadata (the MCP SDK jar has no OAuthAuthorizationServerProvider of
its own, so this is not mirroring an external contract).
exchangeRefreshToken and JwtFilter are the live paths that superseded
them. registerClient and revokeToken were left in place: their overrides
are functional rather than stubs.
