Add comprehensive remote access guide for SSH tunneling

- Add REMOTE_ACCESS.md: Complete guide for monitoring remote servers
  - SSH tunneling setup for restricted networks
  - Multi-server monitoring with port mapping
  - Cloud platform examples (Azure, AWS, GCP, etc.)
  - Helper scripts for Windows/Linux/macOS
  - Troubleshooting and security best practices

- Update README.md: Reference new remote access guide
  - Add SSH tunneling quick start section
  - Link to comprehensive REMOTE_ACCESS.md guide
  - Remove duplicate content

Use cases:
- Monitor cloud VMs with firewall restrictions (only port 22 open)
- Corporate servers with limited port access
- Multiple remote machines simultaneously on different local ports
- Secure encrypted access through SSH tunnel

This completes the documentation for remote monitoring scenarios
where opening additional firewall ports is not possible or desirable.

 ## Advanced Usage
 
+### Remote Server Monitoring (SSH Tunneling)
+
+Monitor servers with restricted firewall access (cloud VMs, corporate servers, etc.) using SSH port forwarding:
+
+```bash
+# On remote server: start dashboard
+./start.sh
+
+# On your local machine: create SSH tunnel
+ssh -L 8081:localhost:8081 user@remote-server.com
+
+# Access in browser
+http://localhost:8081
+```
+
+**Monitor multiple servers simultaneously:**
+Map each server to a different local port and access them all in separate browser tabs.
