Fix Google OAuth for Lovable.dev

The Google sign-in button on my public [login to view URL] property marketplace is visible but fails to authenticate. I have not connected any other OAuth provider yet, so this is a clean slate. What I need from you is simple but precise: • Configure Google OAuth inside my Supabase project, add the correct redirect / callback URIs, and hook it up to the existing [login to view URL] auth flow. • Verify the login works end-to-end on both the web version and the generated mobile build. • Walk me through where to find and safely edit the relevant keys and settings in BOTH the Supabase dashboard and the [login to view URL] editor. I’ll need a concise, step-by-step note so I can repeat the process later. I may need your help confirming I actually have all the right credentials on hand; please factor that into your approach. Full project access will be shared after we start (keys initially masked for safety). The goal is a fully working Google login within two days. A few hours overlap with the Indian time zone will make communication smoother.
