Build the venv on the distro python and drop the obsolete extractors

A uv-managed interpreter lives where the service user cannot execute it, so every
archivebox call as that user died with 'Permission denied' while 0.9 drops privileges
on import; Debian 13 ships python3.13 in apt, so the venv now points at /usr/bin.
0.9 also provisions single-file and readability itself through abx-dl - the two npm
modules no longer exist - and it needs BASE_URL pinned plus tesseract, imagemagick,
ffmpeg, unzip and wget present, or archivebox install reaches for apt as a user that
has no root.
