fix: correct SyncService initialization in sync-scheduler

Fixed TypeScript errors in sync-scheduler:
- Added constructor to initialize SyncService with AutotaskClient
- Fixed AutotaskConfig property names (password, apiIntegrationCode)
- Changed method calls to match SyncService API (incrementalSync, fullSync)
- Fixed syncService references to use this.syncService

This resolves build errors preventing Docker image creation.
