include in-line imports for uv

[Humbedooh]

this is so uv can run it with uv run --script v3/server/main.py and not break all the things.
the steve module still needs to be installed or discoverable somehow..

I don't understand the need for this. The shebang in main.py does the uv run and then it uses pyproject.toml for all the dependencies. Including the steve library.

I just do: $ ./main.py and the server starts properly.
