* Replace custom webhooks implementation with WebhooksCore
Replaced the existing custom webhooks registration and dispatching system with the WebhooksCore library. This involved removing all previous custom webhook classes and interfaces, updating project dependencies, and modifying appsettings and program files to use the new configuration. The update simplifies the webhook handling architecture and leverages the features provided by WebhooksCore.
* Hide API key in Datadog Docker compose file
This change replaces the exposed Datadog API key with a placeholder "<HIDDEN>". This enhances security by preventing the API key from being visible in the version control system.
Deleted an unused commented configuration line in docker-compose-datadog.yml to improve readability and maintainability. This change does not affect the existing tracing configuration or application behavior.
Added `pull_policy: always` to `elsa-server` and `elsa-studio` services in the Docker Compose file to ensure the latest images are always pulled. Updated `elsa-server` environment variables to improve Datadog tracing and monitoring. Adjusted the Dockerfile path for the `elsa-studio` service.
Create new docker-compose files for non-data dog and data dog services. New services include Postgres, cockroachdb, rabbitmq, redis, and elsa-server. Along with the services, a new bash script for migration and various new activities and endpoints are also added for the Elsa server. This set of changes broadens the operational environment of Elsa.
