feat(P01): SLICE-03+04 — PVE API layer (8 scripts) + health-check
SLICE-03 (devops-engineer): ported from coreci/scripts/proxmox/:
api.sh (verbatim), ct-exists.sh, lxc-clone.sh (4GB/16GB, hostname=praxis),
lxc-config.sh (praxis env vars, praxis-firstboot.sh snippet), lxc-start.sh,
stage-snippet.sh (G-101 FIX: bakes GITEA_TOKEN into snippet via sed),
timing.sh (verbatim), rollback.sh (proxy code removed)
SLICE-04 (devops-engineer): health-check.sh adapted for /health:8789
(G-104 FIX: timeout bumped 300s→600s for Docker build margin)
REQ-DEPLOY-03, 04, 05, 07, 08 covered.
