feat: integrate Supabase for database operations and migrations

Add support for Supabase database operations, including migrations and queries. Implement new Supabase-related types, actions, and components to handle database interactions. Enhance the prompt system to include Supabase-specific instructions and constraints. Ensure data integrity and security by enforcing row-level security and proper migration practices.
