refactor: hardcode ports in docker-compose.yml for server deployment

- Remove env variable substitution from docker-compose.yml ports
- Hardcode custom ports directly in compose file: 7080, 7081, 7082, 7700, 6432
- Remove PORT variables from .env.example (now configured in docker-compose.yml)
- Add documentation on how to change ports (edit docker-compose.yml directly)
- Simplifies server deployment - no need to export env variables before docker-compose up

Note: To change ports, edit infra/docker-compose.yml directly

infra/docker-compose.yml
