Fix Docker run issue during agent deployment

[shwetd19]

While deploying the agent, I encountered an issue with docker run. To resolve it, I made the following changes:

1. Dockerfile

   • Replaced pnpm-lock.yaml with package-lock.json in the dependency copy step.
   • Split RUN pnpm prune --prod && chown -R appuser:appuser /app into two separate RUN commands for clarity.

2. ESLint Config

   • Just adjusted the formatting and import order for better consistency.

@shwetd19 are you using npm? this project is built assuming pnpm which is where the issue would probably come from. we may need to make the dockerfile more broadly compatible
