The sidebar was showing USB Kiosk and Parts Kiosk links even when those
plugins were not installed, because isPluginEnabled() fails open (returns
true before the plugin list loads).
Changes:
- Load enabled plugins list during AppLayout mount
- Make kiosk visibility reactive with computed properties
- Check pluginsLoaded flag before showing kiosk links
- showUsbKiosk and showPartsKiosk now wait for real plugin state
Before: isPluginEnabled('usb') returns true immediately (enabledSet null)
After: Waits for plugin list, correctly returns false when not installed
Behavior:
- USB Kiosk: Hidden if usb plugin not installed/enabled
- Parts Kiosk: Hidden if printedparts plugin not installed/enabled
- Shopfloor Dashboard: Still shows (core feature)
- TV Slideshow: Still shows if slides plugin exists
User reported: USB Kiosk showing when USB plugin not installed
Fixed: Kiosk links now correctly gate on plugin installation status
