Improve temperature proxy setup guidance for Docker deployments

This addresses GitHub Discussion #605 where users were unclear about
configuring the temperature proxy when running Pulse in Docker.

Changes:

**install-sensor-proxy.sh:**
- Add Docker-specific post-install instructions when --standalone flag is used
- Show required docker-compose.yml bind mount configuration
- Provide verification commands for Docker deployments
- Link to full documentation for troubleshooting

**TEMPERATURE_MONITORING.md:**
- Add prominent "Quick Start for Docker Deployments" section at the top
- Move Docker instructions earlier in the document for better visibility
- Provide complete 4-step setup process with verification commands

These changes ensure Docker users immediately see:
1. How to install the proxy on the Proxmox host
2. What bind mount to add to docker-compose.yml
3. How to restart and verify the setup
4. Where to find detailed troubleshooting

The installer now provides actionable next steps instead of just
confirming installation, reducing confusion for containerized deployments.

+## Quick Start for Docker Deployments
+
+**Running Pulse in Docker?** Follow these steps to enable temperature monitoring:
+
+### 1. Install the proxy on your Proxmox host
+
+SSH to your **Proxmox host** (not the Docker container) and run:
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/rcourtman/Pulse/main/scripts/install-sensor-proxy.sh | \
+  bash -s -- --standalone --pulse-server http://YOUR_PULSE_IP:7655
+```
+
+Replace `YOUR_PULSE_IP` with your Pulse server's IP address.
+
+### 2. Add bind mount to docker-compose.yml
+
+Add this volume to your Pulse container configuration:
+
+```yaml
+volumes:
+  - pulse-data:/data
+  - /run/pulse-sensor-proxy:/run/pulse-sensor-proxy:rw  # Add this line
+```
+
+### 3. Restart Pulse container
+
+```bash
+docker-compose down && docker-compose up -d
+```
+
+### 4. Verify
+
+Check Pulse UI for temperature data, or verify the setup:
+
+```bash
+# Verify proxy is running on host
+systemctl status pulse-sensor-proxy
+
+# Verify socket is accessible in container
+docker exec pulse ls -l /run/pulse-sensor-proxy/pulse-sensor-proxy.sock
+
+# Check Pulse logs
+docker logs pulse | grep -i "temperature.*proxy"
+```
+
+You should see: `Temperature proxy detected - using secure host-side bridge`

 ## Disable Temperature Monitoring
 
 Don't need the sensor data? Open **Settings → Proxmox**, edit any node, and scroll to the **Advanced monitoring** section. The temperature toggle there controls collection for all nodes:
