Problem
- Starting OAuth from Discourse hit GET /api/oauth/authorize and 302’d to /login?next=/oauth/consent…
- The login page and AuthRedirect always navigated to /console when a session existed, ignoring next, which aborted the OAuth flow and dropped users in the console.

Changes
- Backend (src/oauth/server.go)
  - When not logged in, redirect directly to /oauth/consent?<original_query> instead of /login?next=…
  - Keep no-store headers; preserve the original authorize querystring.
- Frontend
  - web/src/helpers/auth.jsx: AuthRedirect now honors the login page’s next query param and only redirects to safe internal paths (starts with “/”, not “//”); otherwise falls back to /console.
  - web/src/components/auth/LoginForm.jsx: After successful login and after 2FA success, navigate to next when present and safe; otherwise go to /console.

Result
- The OAuth authorize flow now reliably reaches the consent screen.
- On approval, the server issues an authorization code and 302’s back to the client’s redirect_uri (e.g., Discourse), completing SSO as expected.

Security
- Sanitize next to avoid open-redirects by allowing only same-origin internal paths.

Compatibility
- No behavior change for normal username/password sign-ins outside the OAuth flow.
- No changes to token/userinfo endpoints.

Testing
- Manually verified end-to-end with Discourse OAuth2 Basic:
  - authorize → consent → approve → redirect with code
- Lint checks pass for modified files.
