Finished up unit tests for labeller, ai qc and human qc. Also finished the ai qc and human qc endpoints + added human qc html page :)

The image attached here is also a recent addition, the main index.html page showcasing a brief intro of this project, the pipeline, and links to the three html pages.

Also major development: added a way for others to test my project with/without API keys for Gemini or Turso (database), and updated README with implementation steps; will ship soon yayy
