feat(supabase): add credentials handling for Supabase API keys and URL

This commit introduces the ability to fetch and store Supabase API keys and URL credentials when a project is selected. This enables the application to dynamically configure the Supabase connection environment variables, improving the integration with Supabase services. The changes include updates to the Supabase connection logic, new API endpoints, and modifications to the chat and prompt components to utilize the new credentials.
