feat: add healthcheck and config options to JupyterLab Module

[bpmct]

Description

Simplified JupyterLab module configuration and added automatic CSP headers for iFrame embedding for Coder Tasks. The module now works out of the box without requiring users to manually configure Content-Security-Policy headers.

Changes:

• Removed redundant configuration examples from README that duplicated existing module variables
• Added fallback CSP configuration when user doesn't provide custom config
• Cleaned up locals logic with better naming and clearer conditionals
• Updated README to show minimal usage with CSP example for custom configurations
