remove: eliminate floating status panel above editor menu

Removed redundant floating status panel that appeared above the editor menu:

## 🗑️ Floating Status Panel Removal
- **Issue**: Floating status panel in top-right corner duplicated information already in menu
- **Solution**: Disabled `updateStatusDisplay()` method and removed `createStatusPanel()`
- **Result**: Cleaner UI with status information only shown in integrated menu

## 🎯 Changes Made
- **updateStatusDisplay()**: Now returns early without creating floating panel
- **createStatusPanel()**: Method removed since no longer needed
- **Status Integration**: Status information remains available in control panel menu
- **UI Cleanup**: Eliminates visual clutter and redundant information display

## 🚀 User Experience Improvements
- **Cleaner Interface**: No floating overlay competing with menu
- **Single Source**: Status information consolidated in menu only
- **Reduced Clutter**: Simpler, more focused editing experience
- **Better Performance**: No unnecessary DOM element creation/updates

## 🔧 Technical Benefits
- **Code Simplification**: Removed ~40 lines of floating panel code
- **Performance**: No periodic floating panel updates (every 2 seconds)
- **Memory Efficiency**: No floating DOM elements consuming resources
- **Maintainability**: Single status display location to maintain

## ✅ Backward Compatibility
- **Control Panel**: Status information still available in menu
- **Status Tracking**: Real-time tracking continues to work
- **Menu Integration**: All status features remain functional
- **No Functionality Loss**: Only redundant display removed

Added comprehensive test suite with 5 tests verifying floating panel removal.
Interface is now cleaner with status information properly integrated into menu.
