Add high score alert

[harisang]

This PR adds a very simple alerts that checks if the winning score for auctions that made it onchain is larger than some threshold. Very large scores might be an indication of bogus native prices so this is one way to detect those cases.

I realized that currently the tests, as they are set up, will pass if the wrapper function returns True. But this doesn't really check the logic the test implements, so in order to properly see logs and behavior, one needs to run the tests as follows. E.g:

python -m pytest --log-cli-level=DEBUG tests/e2e/high_score_test.py

Code looks good to me.

Do you want to add it to the main loop? Or just have it available for local testing?

In the short term, it would be easy to add a test on Dune. Midterm, we should have a dedicated monitoring repo where we can just easily add a flow to prefect.

Oh good point, forgot to add it in the main loop. Will add it for now as it will make things faster, but it's a good point that we could also use dune for that at some point.
