📋 chore: Document Uncaught Exception Config and Fix Empty Text Export (#11812)

* chore: Prevent empty text parts in conversation export function

Added a check to return an empty array if the text part of the conversation is empty or consists only of whitespace, ensuring cleaner data handling in the export process.

* chore: Update .env.example to include CONTINUE_ON_UNCAUGHT_EXCEPTION variable

Added documentation for the CONTINUE_ON_UNCAUGHT_EXCEPTION environment variable, which allows the app to continue running after encountering uncaught exceptions. This change is not recommended for production environments unless necessary.
