Consider integrating uv with standalone python builds

[jdstrand]

#25969 mentioned that uv is not available in the python-build-standalone releases (only pip is available). influxdb/main has code for working with uv which is (presumably) broken with python-build-standalone. uv can be installed via pip. As such, either:

1. the code for uv is removed and influxdb itself only uses pip (easiest; users can choose to pip install uv in the venv if desired)
2. somehow bootstrap uv as part of setting up the default venv and have influxdb use it instead (not sure of the benefit of this...)
3. somehow adjust our python standalone build to also ship uv

I suggest '1' for now (especially since we already support influxdb3 install package; I suspect most users won't need to know or care if we are using pip or uv) and see what users want, then exploring 2 or 3.

Tentatively assigning @jacksonrnewhouse, please adjust as needed.
