Enhance Immich deployment process by removing old single-container instances and updating service configurations

- Added logic to remove any existing single-container 'immich' instances to prevent conflicts with the new multi-container 'immich_server' stack.
- Updated `build-auto-installer-iso.sh` to utilize configuration files from the `configs/` directory for Nginx and systemd service, ensuring proper setup.
- Modified deployment scripts to ensure the removal of old containers and improved handling of Immich stack creation.
- Updated documentation to reflect changes in service configurations and critical build checklist items.
