epic: Standardized Error Format for Jan

[imtuyethan]

Motivation

The current error handling system in Jan app has too many edge cases, which is challenging to maintain. Our goal is to implement a simplified, standardized error format within the Jan app, focusing on improving maintainability, and providing better context for error handling.

Key Results

• Less hassle: We'll save time by using a standard template instead of creating unique messages for each scenario.
• Efficient troubleshooting: Standardized messages speed up troubleshooting for both users and app pod.
