feat: Windows compatibility (#836)

* feat: win compatibility

* fix

* fix: uptime parse

* opt.: linux uptime accuracy

* fix: windows temperature fetching

* opt.

* opt.: powershell exec

* refactor: address PR review feedback and improve code quality

### Major Improvements:
- **Refactored Windows status parsing**: Broke down large `_getWindowsStatus` method into 13 smaller, focused helper methods for better maintainability and readability
- **Extracted system detection logic**: Created dedicated `SystemDetector` helper class to separate OS detection concerns from ServerProvider
- **Improved concurrency handling**: Implemented proper synchronization for server updates using Future-based locks to prevent race conditions

### Bug Fixes:
- **Fixed CPU percentage parsing**: Removed incorrect '*100' multiplication in BSD CPU parsing (values were already percentages)
- **Enhanced memory parsing**: Added validation and error handling to BSD memory fallback parsing with proper logging
- **Improved uptime parsing**: Added support for multiple Windows date formats and robust error handling with validation
- **Fixed division by zero**: Added safety checks in Swap.usedPercent getter

### Code Quality Enhancements:
- **Added comprehensive documentation**: Documented Windows CPU counter limitations and approach
- **Strengthened error handling**: Added detailed logging and validation throughout parsing methods
- **Improved robustness**: Enhanced BSD CPU parsing with percentage validation and warnings
- **Better separation of concerns**: Each parsing method now has single responsibility

### Files Changed:
- `lib/data/helper/system_detector.dart` (new): System detection helper
- `lib/data/model/server/cpu.dart`: Fixed percentage parsing and added validation
- `lib/data/model/server/memory.dart`: Enhanced fallback parsing and division-by-zero protection
- `lib/data/model/server/server_status_update_req.dart`: Refactored into 13 focused parsing methods
- `lib/data/provider/server.dart`: Improved synchronization and extracted system detection
