Revert "Merge: t-paliad-151 Phase A.5 — compose network_mode: host + Paliadin env-var plumbing. Lifts the DO-NOT-MERGE-before-A.5 gate from da971a7. Dokploy secrets PALIADIN_SSH_PRIVATE_KEY + PALIADIN_KNOWN_HOSTS already registered on mlake (validated SSH key roundtrip via ssh-keygen -y); single-line vars PALIADIN_REMOTE_HOST=100.99.98.203 / PORT=22022 / USER=m also staged. Next deploy is the M1-vs-M2 traefik gate (design §4.2): if paliad.de returns 200/3xx after redeploy, traefik routes under host mode (M2) and the route ships; if 502, revert this merge and revisit decision 1."

This reverts commit a80652a085, reversing
