Complete rebuild: Custom REST API implementation

- Removed MinIO SDK dependency completely
- Built custom HTTP client with AWS S3 signature v4 support
- Created synchronous operations optimized for PowerShell
- Added real progress reporting during transfers
- Implemented performance metrics in result objects
- Fixed null pointer warnings for code quality
- Removed Write-Host usage from test scripts
- Cleaned up unnecessary DLL dependencies

Available cmdlets:
- Connect-MinIO: Enhanced connection with certificate options
- Get-MinIOBucket: List buckets with sorting and filtering
- New-MinIOBucket: Create buckets with region support
- Test-MinIOBucketExists: Check bucket existence
- Get-MinIOObject: List objects with advanced filtering
- New-MinIOObject: Upload files with real progress
- Get-MinIOObjectContent: Download files with progress

This represents a complete architectural overhaul for better PowerShell compatibility and performance.
