chore: Improve code consistency and readability

Refactored the initialization of `LocalSettings` in `channel.service.ts` to only set the properties that have been explicitly provided. This refactoring improves code consistency and readability. Also, removed the unused `initStoreFolders` method from `repository.service.ts` and its related imports. In addition, updated the import style for `PrismaClient` in `repository.service.ts`.

The modified files are:
- src/api/controllers/instance.controller.ts
- src/api/repository/repository.service.ts
- src/api/services/channel.service.ts
- src/api/services/channels/whatsapp.baileys.service.ts

src/api/repository/repository.service.ts
