This change introduces automatically generated `SERVICE_NAME_<SERVICE>`
environment variables for each service within a Docker Compose deployment.
This allows services to reliably reference each other by name, which is particularly
useful in pull request environments where container names are dynamically suffixed.
- The application parser now generates and injects these `SERVICE_NAME` variables
into the environment of all services in the compose file.
- `ApplicationDeploymentJob` is updated to correctly handle and filter these
new variables during deployment.
- UI components and the `EnvironmentVariableProtection` trait have been updated
to make these generated variables read-only, preventing accidental modification.
This commit introduces two new helper functions to standardize resource naming
for pull request deployments:
- `addPreviewDeploymentSuffix()`: Generates a consistent suffix format (-pr-{id})
for resource names in preview deployments
- `generateDockerComposeServiceName()`: Creates SERVICE_NAME environment variables
for Docker Compose services
