Refactored the application's dockerization and added new services

This commit involves significant changes to the application's infrastructure. It refactors the application into two separate services: 'nibiru-auth-api' and 'nibiru-webhook-receiver'. Each service has its corresponding Dockerfile, Nginx & PHP-FPM configuration. It also provides a separate Nginx configuration for handling requests for each service. New environment files, start and stop scripts are introduced to facilitate local and production deployments.
