Fix Failure to Start Simulation LiveStream from Remote Docker Container

[mingxin-zheng]

Fixes #ISSUE_NUMBER

Description

[Copilot]

Pull Request Overview

This PR addresses the livestream startup failure from a remote Docker container by updating import order directives, expanding Docker configuration for CUDA/conda support, enhancing documentation for raytracing mounts, and adjusting build scripts to skip GPU checks during image construction.

• Added isort on/off markers around imports in the replay recording script
• Overhauled the Dockerfile to use a CUDA base image, install required packages, and set up a conda environment with proper entrypoint
• Expanded the README with raysim mount instructions and detailed run/troubleshooting steps

• [nitpick] Inconsistent raysim mount paths are shown (~/raysim:/root/raysim) versus later (<path-to-raysim>:/workspace/...). Consider unifying these examples to avoid confusion for users.

-    -v ~/raysim:/root/raysim:ro \

• Adding GitHub meta SSH keys to known_hosts is incorrect and may introduce security risks. Use ssh-keyscan github.com or a static known_hosts file instead to capture the host's public key.
