feat: allow host port to be configured via environment variable in Docker (#65)

* feat: add reverse proxy support with configurable base path and trust proxy settings

* fix: ensure environment variables are loaded correctly in Docker

- Move dotenv config to the top of server.js
- Update docker-compose.yml to properly handle .env file
- Remove duplicate environment variables section

This ensures BASE_PATH and TRUST_PROXY work as expected in both Docker and local environments.

* refactor: remove hardcoded environment variables from docker-compose.yml

* feat: Allow host port to be configured via .env
