feat(dokploy): add wait-for-postgres script and update Dockerfile and package.json

- Introduced a new script to wait for PostgreSQL to be ready before starting the application.
- Updated the Dockerfile to include a health check for the application.
- Modified the start script in package.json to run the wait-for-postgres script prior to starting the server and migration processes.
- Added the wait-for-postgres TypeScript file to handle connection retries to the PostgreSQL database.
