fix: Configure Supabase SSR cookies for Docker/localhost environment

- Set secure: false for localhost (non-HTTPS) environment
- Configure sameSite: 'lax' to allow cookie transmission
- Ensure path: '/' for site-wide cookie access
- Maintain httpOnly: true for security

This should resolve session persistence issues in Docker containers.
