fix: skip provider button auth only redirect (#3309)
* fix: Return 302 redirect from AuthOnly when skip-provider-button is true

When SkipProviderButton is enabled and a user needs to login, the AuthOnly
endpoint now returns a 302 redirect directly to the OAuth provider instead
of returning 401.

This fixes an issue with nginx auth_request architecture where 401 triggers
error_page handling, which can break redirect flows because nginx overrides
the status code (e.g., to 403), and browsers don't follow Location headers
for non-3xx responses.

Fixes: #334

* test: Add specific OAuth redirect assertions per code review feedback

Improve TestAuthOnlyEndpointRedirectWithSkipProviderButton to verify
that the Location header actually redirects to the OAuth provider's
authorize endpoint with required parameters (client_id, redirect_uri,
state), not just that a Location header exists.

* refactor: Flatten AuthOnly error handling structure

Move the SkipProviderButton check outside of the nested err != nil block
using an if-else structure. This makes the special case more visible and
reduces nesting depth without changing behavior.
