Kiwix was failing to start: its inline bootstrap command had a shell
syntax error (a YAML-wrapped multi-line wget left a dangling `||`), and
the hard-coded sample-ZIM URL returned 404 because Kiwix rotates the
date-stamped filenames monthly.
Replace the inline command with a bind-mounted bootstrap script that
resolves the current ZIM filename from the Kiwix OPDS catalog at startup,
so the download URL never rots. kiwix-serve is also started on port 8080
to match the container port mapping and healthcheck (it defaults to 80).
