🚀 feat: Setup Full CI/CD Pipeline & Unit Tests

📝 Summary

This PR introduces a complete automation infrastructure for the project, including comprehensive Unit Tests, a GitHub Actions configuration, and an enhanced Makefile for a smoother workflow.
The goal is to ensure that no broken code reaches main and that every valid version is automatically packaged into a Docker image.

🛠️ Key Changes

• 🤖 CI/CD Workflow (ci-cd.yaml):

  • Added a pipeline that runs on every push and pull_request.
  • CI: Automatically executes make deps, make test, and make build.
  • CD: Builds a Docker Image and pushes it to GitHub Packages (GHCR) only upon merging to main.

• 🧪 Unit Tests (main_test.go):

  • Authored ~35 tests covering all API endpoints (/login, /schools, /cart, etc.).
  • Includes coverage for Edge Cases, Input Validation, and Session Logic.
  • Utilizes httptest to verify server behavior without needing a running instance.

• ⚙️ Makefile Update:

  • Added a smart make test command.
  • Integrated support for gotestsum for colorful and readable terminal output (with a fallback to standard go test in the CI environment).

✅ Test Plan

1. Ran make test locally in WSL and received a PASS on all checks.
2. Verified that the GitHub Action workflow triggers and succeeds (Green ✔️) on the current branch.
3. Confirmed that the Docker Image builds successfully in the CI environment.
