Martin Bauer 9bd23467f0 Build the venv from the distribution's Python instead of uv ...

The backend now targets 3.11, which is what Raspberry Pi OS ships, so there is
nothing left for uv to solve. It was only ever there to obtain a 3.13 the distro
does not have, and it brought its own problems: the download had to be matched
to the Pi's 32-bit userland by hand, and no armv7 wheel exists for a 3.13 ABI,
so Pillow was compiled from source and needed image headers installed alongside.

apt for the interpreter, python3 -m venv, pip for the rest - and piwheels then
supplies prebuilt armhf wheels for the native dependencies.

A venv cannot be migrated between interpreters (it holds absolute paths into the
one that made it), and `creates:` would keep the old one forever, so check what
built it and rebuild when it does not match the current python3. That is what
carries a device off the uv-installed 3.13 without hand-holding.
