docs: update documentation after sensor proxy deprecation

Update docs to reflect the simplified temperature monitoring architecture:
- Remove references to pulse-sensor-proxy throughout
- Update TEMPERATURE_MONITORING.md to focus on unified agent approach
- Update CONFIGURATION.md, DEPLOYMENT_MODELS.md, FAQ.md
- Remove SECURITY_CHANGELOG.md (proxy-specific security notes)
- Clarify current recommended setup in various guides

 The unified agent (`pulse-agent`) combines host, Docker, and Kubernetes monitoring into a single binary. It replaces the separate `pulse-host-agent` and `pulse-docker-agent` for simpler deployment and management.
 
-> Note: In v5, temperature monitoring should be done via `pulse-agent --enable-proxmox`. `pulse-sensor-proxy` is deprecated and retained only for existing installs during the migration window.
+> Note: For temperature monitoring, use `pulse-agent --enable-proxmox` (recommended) or SSH-based collection. The legacy sensor proxy has been removed. See `docs/TEMPERATURE_MONITORING.md`.
