Update Supabase server instructions and scripts

Updated README.md and scripts to separate the 'web application' and 'Supabase server' in the development process. Modified package.json to include specific scripts for starting, stopping, and generating the Supabase schema. Also adjusted GitHub workflow to start Supabase server before running the app and reduced retention of Playwright report artifacts from 30 to 7 days.
