refactor: update LiveKit integration and clean up unused services

- Changed the base image in Dockerfile to use a lighter node:alpine version.
- Removed unused dependencies from package-lock.json and package.json, including @turbodocx/html-to-docx and jsdom.
- Simplified LiveKit module by removing unnecessary services (LiveKitParticipantService, LiveKitRoomService) and adjusting related schemas and services for better maintainability.
- Updated CollaborationSessionSchema to streamline access token creation and room management.
- Commented out unused imports and services in various modules to enhance code clarity and reduce complexity.
