fix(server): separate compose host port overrides from runtime ports (#137)

## Summary
- split Docker host port overrides onto dedicated compose env vars
- keep the server container listening on port 8000 internally
- align `make server-run` and docs with the separated host-port behavior

## Verification
- `AGENT_CONTROL_SERVER_HOST_PORT=18000 AGENT_CONTROL_DB_HOST_PORT=15432
docker compose -f docker-compose.yml config`
- `AGENT_CONTROL_DB_HOST_PORT=15432 docker compose -f
docker-compose.dev.yml config`
- `make -C server -n run AGENT_CONTROL_HOST=127.0.0.1
AGENT_CONTROL_PORT=18000 AGENT_CONTROL_DB_PORT=15432`

## Tests
- not run (compose/make/docs change only)

 This starts PostgreSQL and Agent Control at `http://localhost:8000`, including
 the UI/dashboard.
 
+To override the exposed host ports, set `AGENT_CONTROL_SERVER_HOST_PORT` and/or
+`AGENT_CONTROL_DB_HOST_PORT` before starting Compose. Example:
+
+```bash
+export AGENT_CONTROL_SERVER_HOST_PORT=18000
+export AGENT_CONTROL_DB_HOST_PORT=15432
+curl -L https://raw.githubusercontent.com/agentcontrol/agent-control/refs/heads/main/docker-compose.yml | docker compose -f - up -d
+```
+
 Verify it is up:
 
 ```bash
 curl http://localhost:8000/health
 ```
 
+If you changed `AGENT_CONTROL_SERVER_HOST_PORT`, use that port in the health check URL.

 Run this in your agent project directory.

 Server runs on http://localhost:8000. The UI expects this base URL by default.
 
+To use non-default local ports with `make server-run`, export
+`AGENT_CONTROL_PORT` for the server listen port. If you also want the local
+Postgres container exposed on a different host port, set
+`AGENT_CONTROL_DB_HOST_PORT` and point the server at the same value with

 ## Configuration
 
 Server configuration is driven by environment variables (database, auth, observability, evaluators). For the full list and examples, see the docs.
