feat: achieve CLI parity with Central UI

Add 33 new management message records, ManagementActor handlers, and CLI
commands to close all functionality gaps between the Central UI and the
Management CLI. New capabilities include:

- Template member CRUD (attributes, alarms, scripts, compositions)
- Shared script CRUD
- Database connection definition CRUD
- Inbound API method CRUD
- LDAP scope rule management
- API key enable/disable
- Area update
- Remote event log and parked message queries
- Missing get/update commands for templates, sites, instances, data
  connections, external systems, notifications, and SMTP config

Includes 12 new ManagementActor unit tests covering authorization,
happy-path queries, and error handling. Updates CLI README and component
design documents (Component-CLI.md, Component-ManagementService.md).
