Adds bootstrap-host.sh (one-time, run as root on a fresh Proxmox host) and
fix-lxc-apparmor.sh, the fixed-content script it installs. The sudoers
rule it wires up only ever invokes that one root-owned script with a VMID
argument - deliberately not a broader rule like `tee -a <conf>` or
`sh -c '...'`, since those only restrict the command's own argv, not
stdin/heredoc content, letting the caller write arbitrary lines to any
200-299 container's config instead of just this one fixed line.
create-graylog-lxc.sh now tries `sudo -n fix-lxc-apparmor.sh` first and
falls back to the existing manual instructions if that sudoers rule isn't
present yet - fully backward compatible with hosts that haven't run
bootstrap-host.sh.

The CI runner setup was done by hand this session (download, verify,
register, systemd unit) - script it the same idempotent way as
install-graylog.sh so a fresh deployment can reproduce it instead of
requiring manual SSH archaeology. Wire it into create-graylog-lxc.sh's
payload copy, and add step 9 to both READMEs covering the one-time setup.
