Browser Control Panel: UI Improvements and Framework Integration

Summary

This PR implements comprehensive improvements to the browser control panel, including viewport scaling fixes, status indicator corrections, proper centering behavior, and framework compliance verification. The panel now integrates seamlessly with Agent Zero's component system and provides a better user experience.

Changes Made

1. VNC Viewport Scaling & Mobile Responsiveness

Files: webui/components/browser-control/browser-panel.html

• Implemented comprehensive responsive CSS for mobile devices:
  • Desktop: 800x800px panel
  • Tablets (≤1024px): 700x600px panel
  • Mobile (≤768px): Near fullscreen with proper margins
  • Extra small (≤480px): Optimized for small screens`)

2. Status Indicator Colors

Files: webui/components/browser-control/browser-control-icons.html

• Changed browser control indicator dot from green to blue (#4a9eff) to match Agent Zero's accent color
• Maintains visual consistency with idle state color scheme

3. Browser Panel Positioning

Files: webui/components/browser-control/browser-panel.html

• Implemented proper centering logic that triggers every time panel opens
• Uses CSS transforms for instant centering while calculating final position
• Added $watch on isVisible to recenter panel on each open

4. Auto-Open Behavior Removed

Files: webui/components/browser-control/browser-control-store.js

• Simplified checkVncAvailability() to only update state, not trigger UI changes

5. Integration Improvements

Files: webui/js/browser-control-integration.js

• Simplified to only provide global helper functions (showBrowserControl, hideBrowserControl, toggleBrowserControl)
• Better approach: Store polling replaces message parsing

6. Framework Compliance Verification

Analysis: Verified browser control panel follows Agent Zero's component and modal system patterns

• ✅ Proper <x-component> integration in index.html
• ✅ Correct Alpine.js store pattern with createStore()
• ✅ Consistent use of Alpine directives (x-data, x-show, x-if, x-bind)
• ✅ Follows same structure as other components (preferences, memory dashboard)
• ✅ Correctly implemented as floating panel (not modal) with draggable behavior
