AMP-187 Trigger api test as downstream of building docker image(push to main)

[samirgarg]

Summary of Changes

.github/workflows/ci-build-publish.yml

• Renamed job: api-test → API-Test-PR

• Added new job API-Test-Main:

  • Runs on trigger_docker (push to main/master)
  • Depends on Build-Docker and Artefact-Version
  • Tests the published Docker image from GitHub Container Registry
  • Uses DOCKER_IMAGE environment variable to pull and run the image

apiTest/docker-compose.yml

• Added image: ${DOCKER_IMAGE} field to the app service
• Now supports both modes:
  • When DOCKER_IMAGE is set: Uses the published image
  • When DOCKER_IMAGE is not set: Builds from source using Dockerfile
• Added comments explaining the conditional behavior

Gradle wrapper

• Added gradle wrapper for all gradle tasks

Result

Single docker-compose file works for both PR (build from source) and push (use published image) scenarios, controlled by the DOCKER_IMAGE environment variable.
