complete all stack READMEs to the 9-section template

Existing content preserved and reordered to the canonical section order;
missing sections generated from each stack's compose data (ports, volumes,
env vars, image links). Fixes copy-paste errors in Dockhand sections
(qbittorrent pointed at archivebox; invokeai/thunderbird said SERVICENAME)
and persistant->persistent typos in gatus.
