docs(proxmox): document HA, corosync tuning, diagnostic tools and mail relay

Browse Source 
Following the 2026-04-20 cluster outage, the cluster README now covers
HA resource limits, corosync token tuning (10s tolerance for USB glitches),
rasdaemon/netconsole/kdump diagnostic stack on pvemini, mail relay via
mail.romfast.ro with SMTP auth, OOM alerting via cron, and swap on pveelite.

VM 109 README now clearly states it was removed from HA and is only
started by the weekly DR test script.
