refactor(docker): update webserver configuration in docker-compose file

- Changed webserver service to build from local Dockerfile instead of using a remote image.
- Updated image name to 'intellidocs-ngx:local' and set pull policy to 'never'.
- This change facilitates local development and testing of the IntelliDocs application.
