Release v1.2.0: Integrate osquery for enhanced system information

Major Features:
- Integrated osquery for comprehensive system information gathering
- Added OsqueryService for executing SQL queries against system tables
- Implemented Osquery Console tab for interactive SQL queries

System Info Improvements:
- Enhanced system info collection using osquery tables
- Added support for multiple GPU detection
- Improved memory detection with proper GB formatting
- Fixed OS Architecture detection (x64/x86)
- Better network interface detection (IPv4 only)
- Human-readable timestamp formatting

UI/UX Enhancements:
- Added window resizing with corner drag support
- Implemented dynamic window sizing (SizeToContent)
- Added ScrollViewer for content overflow
- Improved IP address formatting with bullet points
- Added field labels to all system info displays
- Set minimum/maximum window size constraints

Bug Fixes:
- Fixed XAML StackPanel Spacing property issue
- Merged duplicate MainWindow constructors
- Fixed non-nullable field warnings
- Fixed EventHandler nullability signatures
- Removed redundant hostname/OS name fields
- Fixed GPU registry query to detect all GPUs
