FIX: login redirect to root path in subfolder setup

When Discourse is served from a subfolder (e.g., /forum), logging in from the lo…gin page itself would incorrectly redirect users to the root domain (/) instead of the subfolder root (/forum/). The issue had two causes: 1. The login path check in `extract_redirect_param` used the Rails `login_path` helper which returns "/login" without the subfolder prefix. When the browser sent the full path "/forum/login", the check `starts_with?("/login")` failed to match, treating it as a valid redirect target instead of rejecting it. 2. The `enter` method didn't apply the subfolder prefix when falling back to the root path "/". Fixed by: - Building the full login path with `Discourse.base_path` for accurate matching in subfolder setups - Wrapping the fallback "/" with `path()` in `enter` to respect the subfolder configuration - Extracting redirect validation into `valid_redirect_uri?` for clarity Ref - meta/t/386619
