Fix Google OAuth for Lovable.dev

Job ID: 40178087

Budget: ₹600 – ₹1,500 INR

The Google sign-in button on my public Lovable.dev 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 Lovable.dev 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 Lovable.dev 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.
