feat: add admin CLI for project management

- User management (list, create, delete, reset-password)
- Data CRUD for all 32 collections
- Import/export with JSON support
- Worker/queue management (status, jobs, retry, trigger)
- Webhook management (list, test, deliveries, retry)
- Agent management (list, CRUD, tasks, trigger, activity)
- Health diagnostics (check, errors, stats)
- JSON output mode (--json flag)
- Run via: npm run cli -- <command>
