✨ Feat: uv and minio bucket setup

[IsaacGemal]

Low hanging fruit PR - just some simple quality of life tweaks for local setup and build times.
UV to make docker compile times a bit quicker (we're not using UV for the env, just literally to replace pip).
Give it a shot, it's a nice upgrade and it doesn't impact anything else.
Adding the minio creation in the docker yml because a person shouldn't have to know to run this very specific command from make reset to get the entire setup running.

	docker-compose exec object sh -c "mc alias set object http://localhost:9000 fake_key fake_secret && \
		mc mb object/mcbench-backend-object-local && mc anonymous set download object/mcbench-backend-object-local && \
		mc mb object/mcbench-object-cdn-local && mc anonymous set download object/mcbench-object-cdn-local"

And of course tweaking the seed script.

I think this is all fine except maybe the deps-builders dockerfile.

This is my initial attempt.
