Implement CI/CD gitlab pipeline

SUMMARY

Configure the .yml file to run the gitlab pipelines. Configure redis instance

Current pipeline structure

• Stages: test, build, pages (docker stage commented out)
• Jobs: test, lint, build_docs, pages
• Active Features: Poetry caching, parallel testing, code coverage, documentation builds
• Disabled Features: Security scanning (SAST, Secret Detection, Dependency Scanning), Docker builds

Current issues

1. Dependency installation bypasses Poetry lock file

Problem:

• The test job installs pytest-xdist via poetry run pip install pytest-xdist (line 82)
• This bypasses Poetry's dependency management and lock file
• Could result in version drift and non-reproducible test environments

2. Documentation Dependencies Not Version-Pinned

Problem:

• build_docs job installs dependencies via pip without version pinning (line 127)
• Not using Poetry's dependency groups
• Non-reproducible documentation builds

3. Security scanning disabled

Problem:

• SAST, Secret Detection, and Dependency Scanning templates commented out (lines 9-11)
• No security vulnerability detection in pipeline
• Potential security issues in production

4. Missing type checking

Problem:

• No static type checking (mypy, pyright) in pipeline
• Python type hints not validated
• Runtime type errors not caught early

5. Docker builds disabled

Problem:

• Docker build jobs commented out (lines 159-235)
• No automated container builds
• Manual deployment process

ACCEPTANCE CRITERIAS / GOALS

• Gitlab pipelines should be configured and scheduled
