feat: add container resource configuration prompts in setup wizard

Introduced interactive prompts for configuring container resource settings (CPU, memory, disk, persistence) during the setup wizard. Updated the default configuration to include these settings and improved user guidance on their implications for Docker, Singularity, and Modal backends. This enhancement aims to streamline the setup process and provide users with clearer options for resource management.
