Migrate the Furni Editor from REST API to WebSocket-based communication
using custom packet handlers (10040-10046). The editor now communicates
directly with the emulator for all CRUD operations on furniture items.
Key changes:
- Replace REST API calls with WebSocket composers/parsers for search,
edit, create, and delete operations
- Read furnituredata.json path from renderer-config.json for asset
management
- Improve search UI with larger fonts, better contrast, and click-to-copy
ID functionality with toast notification
- Compact edit view layout with collapsible sections and visual dividers
- Remove unused Create tab (creation handled via edit workflow)
- Add isModerator guard for admin-only access
- Support search by ID, name, or sprite ID with type filtering
