Improvements to category tree UX:
- Auto-expand parent category after creating subcategory at any nesting level
- Recursive ancestor expansion using elegant DOM traversal with .closest()
- Smooth scroll to newly created category with visual feedback
- Replace icon buttons with text: "Развернуть все" / "Свернуть все"
- Eliminates confusion between "+" for adding category vs expanding tree
Technical implementation:
- URL parameter ?expand=<parent_id> to preserve state after page reload
- Recursive expandAncestors() function traverses up the DOM tree
- Uses :scope selector for precise parent-child relationship queries
- Auto-cleans URL parameter after expansion using history.replaceState()
