refactor: update LiveKit egress service and module structure

- Removed the `livekit.egress.ts` file and replaced it with `livekit.egress.service.ts` for better clarity and consistency in naming.
- Updated `livekit.module.ts` to reflect the new import path for the `LiveKitEgressService`.
- Enhanced `livekit.room.service.ts` to utilize the new egress service structure, including improved egress configuration for recording sessions with dynamic file output settings.
- Removed the `rootDir` property from `tsconfig.json` to streamline the TypeScript configuration.
