Subject: [PATCH] Add docker-compose config for host-based Fleet Server and new
 `/ping` route

- Introduce `docker-compose.fleet-host.yml` allowing Elastic Agent to connect to a host-installed Fleet Server.
- Add `pingRoute` to provide a simple `/ping` endpoint returning "pong" with a timestamp.

+## Usage (Windows + WSL host Fleet Server):
+## 1) Stop containerized Fleet services to free port 8220:
+##    docker compose stop fleet-server elastic-agent
+## 2) Install Fleet Server on WSL (see commands I provided), verify http://localhost:8220/api/status
+## 3) Start Elastic Agent pointing to host Fleet:
+##    docker compose -f docker-compose.yml -f docker-compose.fleet-host.yml up -d elastic-agent
+## 4) Verify in Kibana → Fleet → Agents: Fleet Server (host) healthy; Elastic Agent (container) healthy.
