feat: migrate to docker-compose with selfhosted-supabase-mcp

- Replace legacy directory structure (api/, db/, functions/, logs/, pooler/) with single docker-compose.yml based self-hosted setup - Add selfhosted-supabase-mcp TypeScript MCP server for database management - Add .dockerignore for Docker build context - Update .gitignore to exclude .env files, volumes/, backups, logs
