Migrate Quarry to use Poetry for dependency management.

[Vanshika110]

Replaced requirements.txt with pyproject.toml/poetry.lock and updated Dockerfile for clean builds.
Task: T397332

The dependency list will need to be pruned to only include direct dependencies and not transient ones to get full advantage of a proper dependency manager. That can be done on this patch or in a follow-up.

More critically, with these changes the development environment fails to even start:

web-1  | Traceback (most recent call last):
web-1  |   File "/app/wsgi.py", line 1, in <module>
web-1  |     from quarry.web.app import create_app
web-1  |   File "/app/quarry/web/app.py", line 1, in <module>
web-1  |     from flask import current_app, Flask, render_template, g, Response
web-1  | ModuleNotFoundError: No module named 'flask'

Similarly the tox checks need to be fixed, see the failing CI run. Please fully test your changes locally before sending them for a proper review.

Hi @supertassu , I’ve updated the workflows to use actions/checkout@v4 with ${{ github.head_repo.full_name }} and confirmed the changes are present in this branch. However, the same issue still persists— it’s still failing at the git checkout step.
I also tried switching the branch reference in the GitHub UI (to ensure the workflow uses the latest head repo), but the same issue continues. It seems GitHub Actions might still be using an older cached workflow or configuration.
Could you please take a look or let me know if there’s any additional repository-side configuration that might be affecting it?

@supertassu Can you please review it again, I made the changes which you requested earlier, looking for guidance!

Did you test these changes locally? The web container is failing to start for me:

These need porting to the Helm manifests as well.
