docs(audit): document observability stack + Saturday OAM day plan
Operator-defined monitoring architecture (no tool duplication):
- Beszel (Cloudron VPS): CPU/RAM/disk metrics on all Proxmox hosts via Tailscale
- Uptime Kuma (Cloudron VPS): up/down alerting via Pushover
- LibreNMS (VMID 104, on-prem): SNMP polling for switches (non-Tailsale gear)
- Home Assistant (VMID 100, on-prem): power/temp instrumentation + alerting
Saturday 2026-08-01 is designated OAM Day: goal is 100% instrumentation
coverage across all four tools + centralized syslog.
