feat: add no-arg RevokeToken and GetAccessToken

Adds a no-arg RevokeToken() overload that revokes the currently
authenticated session without requiring the caller to manually pass
the access token. Also exposes GetAccessToken() on both InfisicalSdk
and ApiClient so callers can retrieve the token if needed.

Previously, all auth login methods (LdapAuthLogin, UniversalAuthLogin,
etc.) stored the token internally with no way to retrieve it, making
it impossible to call RevokeToken(token) after authentication.
