Add unused macros detection feature

[chhoumann]

Summary

Add functionality to detect and highlight macros that are no longer used or referenced anywhere in QuickAdd configurations.

Problem

Over time, users accumulate many macros and may:

• Create test macros that are never deleted
• Remove references to macros but forget to delete the macro itself
• Have orphaned macros from changed workflows
• Struggle to identify which macros are actually in use

Proposed Solution

Add "Unused Macros Detector" feature in QuickAdd settings:

Detection Logic

• Scan all Choice configurations for macro references
• Check for macros called via API in user scripts
• Identify macros never referenced anywhere
• Show last-used dates if available

UI Features

• "Find Unused Macros" button in settings
• List view showing potentially unused macros
• Confirmation before bulk deletion
• Export unused macros before deletion (for backup)

Implementation Ideas

• Scan choice configurations for macro calls
• Parse user scripts for quickAddApi.executeChoice() calls
• Track macro usage statistics over time
• Safe deletion with confirmation dialogs

Benefits

• Cleaner macro organization
• Reduced cognitive load when browsing macros
• Better performance with fewer unused macros
• Easier maintenance of large macro collections
