Category classification

The target of this issue is to allow user to create rules and auto-select tracked payment category by a shop (description)

add the event listener in Bill editing page, Listen for category select changes.

if user has notification tracker, check if description is already categorized. If both are true, display "uncategorize" somewhere nearby. Only if second one is negative - display the popup with text - do you want to auto-select {selectedCategory} for {description}?

if user selected "yes" in popup - map the description to category in special place of SharedPreferences.
