Let ArchiveBox reach 0.9 instead of staying on 0.7.4

uv pip install --system targets the container's Python 3.11, and every ArchiveBox
release from 0.9 on requires 3.13, so the resolver silently fell back to 0.7.4.
The package now lives in its own 3.13 venv, with the interpreter outside root's
home because ArchiveBox drops privileges while importing. The expect block is
gone: init and createsuperuser both run unattended now, and the server moved to
its new default port.
