Function library 🛠️

In order to measure how well the functions created are working, to allow the creation of functions for convenient use in AI assistants, to obtain metrics and to visualize the history of the last functions executed, the Function Library is created.

Feedback
Pain: Functions were too hidden inside each assistant. To modify a function that should apply to all wizards, it was necessary to log into a particular one, which was confusing and inefficient. In addition, there was no clarity about their performance and no history to understand when and how they were being executed.

Solution:
All functions are centralized in the new Function Library, accessible from the Training section. Here users can create, edit and manage functions in one place, reviewing metrics and their execution history. This allows functions to be managed consistently, without relying on a specific wizard and with full visibility of their performance.
