Frank 2406641bc6 fix(dankserver): mount /mnt/entropy from its LUKS mapper at boot
The crypttab entry named the md RAID array UUID (61bd6eaf-...) where a luks
entry takes the LUKS container UUID (cd86c728-...), so
systemd-cryptsetup@entropy.service could never produce /dev/mapper/entropy and
the fstab entry could not resolve either; the volume only appeared when a
desktop session let udisks2 unlock it, which kept the broken boot path hidden
for a year. The keyfile was wrong as well: 27 bytes, i.e. the 26-character
passphrase plus a trailing newline, and cryptsetup hashes the file whole.

Records the host config as dankserver/host/{crypttab,fstab} (the dankclaw/host
precedent), rewrites the Entropy Volume page to own the chain, the UUID law and
the keyfile contract, and comments out the now-unmountable /dev/md0 line.

Proven on the host: /etc/{crypttab,fstab} byte-identical to the repo copies,
reboot into 7.0.0-42-generic mounts /mnt/entropy from /dev/mapper/entropy, all
12 containers returned, frank-archon back to 141 t/s (was 6.7 t/s on a wedged
amdgpu queue). ./tests/run.sh: ALL TESTS PASSED (749).
