Praxis CI 00e39a3f85 feat(milestone): merge phase/01 operator-foundation → milestone/v0.4-operator-tier
Phase 1 complete — Operator Foundation:
- Postgres 16 in Docker-in-LXC (asyncpg pool, 5-table schema, PgStore, migrations)
- Operator auth (argon2id, signed stateless cookies, slowapi 5/min rate limit)
- VC issuer key migration SQLite→Postgres (archive-before-active, R-VC-MIG-01)
- Operator bootstrap CLI (create-operator.py, idempotent)
- Backup cron script + G-008 restore drill
- Graceful degradation (server starts without Postgres)
- 272 tests pass, 33 skip (Postgres-requiring), 0 fail

# Praxis — Create a Proxmox LXC container from a template via REST API.
#
# Uses the POST /nodes/{node}/lxc endpoint with ostemplate=<volid>
# (create-from-template) instead of the storage clone endpoint. The
# clone endpoint rejects API tokens (`user != root@pam` guard), but
# the create endpoint accepts them — so this path works end-to-end
# with a PVEAPIToken. Pure REST, no SSH.
#
# Env: PROXMOX_API_URL, PROXMOX_API_TOKEN, PROXMOX_NODE,
# PROXMOX_STORAGE, PROXMOX_TEMPLATE_VOLID
# Args: $1 = target VMID (from pve_nextid)
# Stdout: the new VMID (integer)
# Exit: 0 on success, 1 on failure
