🪲 BUG-#216: Fix traceback_error ignoring error parameter

[FernandoCelmer]

Description

Fix traceback_error() which accepted an error parameter but never used it, relying on sys.exc_info() instead. This produced empty/wrong tracebacks when called outside an active except block.

Issue: 📌 ISSUE-#216

Changes

• Replace sys.exc_info() + format_stack() with traceback.format_exception(type(error), error, error.__traceback__)
• Remove unused import sys
• Traceback now always reflects the actual error, regardless of call context

Type of change

• Bug fix (non-breaking change which fixes an issue)
