[WIP] Fix python versioning issues for fridge data upload

[Copilot]

Thanks for asking me to work on this. I will get started on it and keep this PR's description up to date as I form a plan and make progress.

Setting up a new fridge to upload data - running into python versioning issues. Since I am using a dict, i need at least python 3.9. This fridge had python3.7, and now the script finds python3.7 and defaults to it. I ran 'python3' from cmdline and installed python 3.13, so it's got the correct python now, the script just needs to (if there is an error on push_metrics : type not subscriptable, or it realizes python < 3.9, try to find another python and use that. Additionally, add a 'manual override' in the worst case to check for a designated python exe location specified in .env and use that.
