feat: implement comprehensive Status Matrix Module

StatusView.vue:
- Complete status matrix with 5 core capabilities (postNotifications, exactAlarm, channelEnabled, batteryOptimizations, canScheduleNow)
- Real-time status collection from plugin methods
- Actionable buttons for fixing issues (Request Permission, Open Settings, etc.)
- Comprehensive diagnostics export with JSON copy-to-clipboard
- Error handling and user feedback
- Responsive design with modern UI

StatusCard.vue:
- Redesigned as individual status item cards
- Color-coded status indicators (success/warning/error/info)
- Action buttons for each status item
- Hover effects and smooth transitions
- Mobile-responsive layout

Features implemented:
- Dynamic plugin import and status collection
- Parallel status checking (notificationStatus, permissions, exactAlarmStatus)
- Action handling for permission requests and settings navigation
- Diagnostics export with app version, platform, timezone, capabilities
- Error display and recovery
- Modern glassmorphism UI design

This completes the Status Matrix Module from the implementation plan.
