barsa a23a5593f7 refactor(bff): restructure service architecture with clearer naming conventions
- Rename integration orchestrators to facades:
  - WhmcsConnectionOrchestratorService → WhmcsConnectionFacade
  - FreebitOperationsService → FreebitFacade
  - SalesforceService → SalesforceFacade

- Rename module orchestrator:
  - SimOrchestratorService → SimOrchestrator

- Rename aggregators for clarity:
  - MeStatusService → MeStatusAggregator
  - UserProfileService → UserProfileAggregator

- Move integration facades to dedicated facades/ folders:
  - whmcs/facades/whmcs.facade.ts
  - salesforce/facades/salesforce.facade.ts
  - freebit/facades/freebit.facade.ts

This establishes clearer architectural boundaries between:
- Facades: unified entry points for integration subsystems
- Orchestrators: coordinate workflows across multiple services
- Aggregators: read-only data composition from multiple sources
