docs(drift): fleet drift report with executive briefing format

Browse Source 
Dedicated drift report covering package/service/tuning/security
inconsistencies across all 7 Proxmox hosts. Executive briefing at the
top (what needs decisions, quick severity summary), detailed matrices
in appendixes.

Key drift findings:
- lldpd inactive on tsys1 (blind spot in topology)
- tsys9 missing 2 SSH keys vs fleet standard
- iperf3 missing on tsys9, net-tools missing on tsys1/6/7
- sysstat missing on tsys5, nvme-cli missing on tsys4/5
- tsys4 tuning drift: 16MB TCP buffers, low backlog, wrong tuned profile
- rsyslog + snmpd + beszel inactive fleet-wide (Saturday OAM Day items)
- noatime only on tsys5 root fs (all others use relatime)

Added perf/scripts/probe-drift.sh as a portable reusable drift probe.
