Add folder organization to Favorite Wearables

[AmyLynnLaville]

Adds folder organization support to the Favorite Wearables floater.

This allows users to create folders under #Wearable Favorites, select folders from the Favorite Wearables floater, drag/drop favorites into folders, and use a right-click Assign to Folder submenu to assign favorite wearables to folders.

Existing Favorite Wearables behavior remains available through the root “All Favorites” view.

Summary

• Adds folder selector to Favorite Wearables
• Adds create/rename/delete folder support
• Adds de-duplicated All Favorites view
• Adds right-click Assign to Folder submenu
• Preserves current folder view after assigning items
• Uses existing inventory links; does not alter original wearable items

Testing

Tested on Windows 11 with Firestorm 7.2.5 source build.

Verified:

• Create folder
• Rename folder
• Delete folder
• Drag/drop favorite into folder
• Assign favorite to folder via right-click menu
• Assigning from one folder does not switch view back to All Favorites
• Duplicate assignment prevention
• Existing Favorite Wearables root view still works

Notes

No server-side changes.
No inventory migration required.
Existing users can continue using Favorite Wearables as before.

Thank you for the contribution and apologies for not looking into it earlier. The changes itself look good and I like the idea of adding folders/categories. I would like to suggest a few smaller UI changes regarding the buttons:

• How about moving the buttons related to the folders/categories to the right of the combobox? Then it would be more obvious they are related to that.
• I'm a bit undecided about the single letter buttons for removing and deleting a folder/category as those small action buttons usually use icons. But using the trashcan icon could lead to confusion because then there would be two buttons with the same icon deleting different things - and they would be placed directly under each other.
