Reorganize Proxmox documentation with clear structure and VM/LXC mapping

## Changes

### Documentation Reorganization
- **README.md**: Complete restructure with logical sections
  - Infrastructure General (proxmox-ssh-guide.md)
  - LXC Containers (oracle-database-lxc108.md)
  - Virtual Machines (vm201-*.md)
  - Cluster-Wide Resources (cluster-ha-monitor.sh, ups/)
  - Archived/Decommissioned (archived-vm107-monitor.sh)
  - Added quick navigation "Am nevoie să..." section
  - Added recommended workflows
  - Added complete directory structure map

- **proxmox-ssh-guide.md**: Added documentation references section
  - Clear links to all related documentation
  - When to use each document
  - Quick start snippets for each resource

### File Renames for Clarity
- `certificat-letsencrypt-iis.md` → `vm201-certificat-letsencrypt-iis.md`
- `troubleshooting-vm201-backup-nfs.md` → `vm201-troubleshooting-backup-nfs.md`
- `ha-monitor.sh` → `cluster-ha-monitor.sh`
- `vm107-monitor.sh` → `archived-vm107-monitor.sh`

### New Documentation
- **vm201-windows11.md**: Complete VM 201 documentation
  - Hardware configuration
  - Installed services (IIS, SQL*Plus, WinNUT, RDP)
  - Network configuration
  - Backup and recovery procedures
  - Common troubleshooting

## Benefits
- Clear naming convention: VM/LXC/Cluster prefixes
- Central index in README.md with navigation
- Cross-references between documents
- Complete VM 201 documentation suite
- Clear archival of decommissioned resources
