feat: change default ports to non-standard values and improve configurability

Migrate all AgentEx ports from commonly-used generic ports to unique,
less standard ports to avoid conflicts with other local services:

- AgentEx API: 5003 → 5718
- ACP Server: 8000 → 8718
- Health Check: 80 → 8080
- Multi-agent example offsets: 8000-8003 → 8718-8721

All ports remain fully configurable via environment variables
(AGENTEX_BASE_URL, ACP_PORT, HEALTH_CHECK_PORT) and manifest
configuration. This change updates defaults across:

- Core SDK (environment_variables.py, _client.py, base_acp_server.py)
- CLI templates and deploy handlers
- 23 example/tutorial Dockerfiles
- 25 manifest YAML files
- 41 example test files and dev notebooks
- Multi-agent example scripts and documentation

Note: .github/workflows/*.yml still needs updating but requires
workflow scope token.
