Update Proxmox HA monitoring script - remove qdevice support

Changes: - Remove qdevice verification (qdevice no longer exists in cluster) - Fix cluster nodes detection (updated pvecm status output format) - Add --help parameter with complete usage documentation - Update notification templates (remove qdevice references) - Simplify quorum check (only verify total_votes = expected_votes) The script now correctly monitors: - HA Services (pve-ha-lrm, pve-ha-crm) - Cluster Quorum (3/3 votes) - Online nodes (3 nodes detected via Membership information) Tested successfully on pvemini.romfast.ro (10.0.20.201) Status: SUCCESSFUL with all checks passing Also updated proxmox-ssh-guide.md with current cluster configuration. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

 ## Note Importante
-1. **Întotdeauna fă backup** înainte de modificări majore
-2. **Folosește storage local-zfs** pentru performanță optimă
-3. **Pentru Windows 11** folosește placa de rețea e1000 în loc de VirtIO pentru compatibilitate
-4. **CPU type 'host'** oferă performanțe maxime cu KVM=1
-5. **Testează conexiunea SSH** înainte de automatizări
+
+### Cluster și High Availability
+1. **Clusterul are 3 noduri** - Quorum necesită 2/3 noduri online
+2. **Întotdeauna fă backup** înainte de modificări majore
+3. **Storage sincronizat** - backup și backup-nfs sunt disponibile pe toate nodurile
+
+### Performance și Configurații
+4. **Folosește storage local-zfs** pentru performanță optimă VM-uri/containere
+5. **Pentru Windows 11** folosește placa de rețea e1000 în loc de VirtIO pentru compatibilitate
+6. **CPU type 'host'** oferă performanțe maxime cu KVM=1
+7. **VM 201 (Windows 11 activ)** rulează pe local-zfs pentru performanță
+8. **VM 107 (Windows 7)** este oprit - considerat legacy
+
+### Backup și Siguranță
+9. **Backup zilnic la 02:00** pentru toate containerele active și VM-ul 201
+10. **Retention policy:** 1 daily + 1 weekly
+11. **Compression zstd** pentru backup-uri eficiente
+12. **Testează conexiunea SSH** pe toate nodurile înainte de automatizări
+
+### Containere Active
+13. **8 containere LXC** cu diverse servicii (Portainer, Minecraft, Coolify, PBS, Flowise, Gitea, Oracle)
+14. **Container 103 (PBS)** - Proxmox Backup Server pentru backup-uri dedicate
