Chris Lu ff271aba16 Migrate from deprecated azure-storage-blob-go to modern Azure SDK

Migrates Azure Blob Storage integration from the deprecated
github.com/Azure/azure-storage-blob-go to the modern
github.com/Azure/azure-sdk-for-go/sdk/storage/azblob SDK.

## Changes

### Removed Files
- weed/remote_storage/azure/azure_highlevel.go
  - Custom upload helper no longer needed with new SDK

### Updated Files
- weed/remote_storage/azure/azure_storage_client.go
  - Migrated from ServiceURL/ContainerURL/BlobURL to Client-based API
  - Updated client creation using NewClientWithSharedKeyCredential
  - Replaced ListBlobsFlatSegment with NewListBlobsFlatPager
  - Updated Download to DownloadStream with proper HTTPRange
  - Replaced custom uploadReaderAtToBlockBlob with UploadStream
  - Updated GetProperties, SetMetadata, Delete to use new client methods
  - Fixed metadata conversion to return map[string]*string

- weed/replication/sink/azuresink/azure_sink.go
  - Migrated from ContainerURL to Client-based API
  - Updated client initialization
  - Replaced AppendBlobURL with AppendBlobClient
  - Updated error handling to use azcore.ResponseError
  - Added streaming.NopCloser for AppendBlock

### New Test Files
- weed/remote_storage/azure/azure_storage_client_test.go
  - Comprehensive unit tests for all client operations
  - Tests for Traverse, ReadFile, WriteFile, UpdateMetadata, Delete
  - Tests for metadata conversion function
  - Benchmark tests
  - Integration tests (skippable without credentials)

- weed/replication/sink/azuresink/azure_sink_test.go
  - Unit tests for Azure sink operations
  - Tests for CreateEntry, UpdateEntry, DeleteEntry
  - Tests for cleanKey function
  - Tests for configuration-based initialization
  - Integration tests (skippable without credentials)
  - Benchmark tests

### Dependency Updates
- go.mod: Removed github.com/Azure/azure-storage-blob-go v0.15.0
- go.mod: Made github.com/Azure/azure-sdk-for-go/sdk/storage/azblob v1.6.2 direct dependency
- All deprecated dependencies automatically cleaned up

## API Migration Summary

Old SDK → New SDK mappings:
- ServiceURL → Client (service-level operations)
- ContainerURL → ContainerClient
- BlobURL → BlobClient
- BlockBlobURL → BlockBlobClient
- AppendBlobURL → AppendBlobClient
- ListBlobsFlatSegment() → NewListBlobsFlatPager()
- Download() → DownloadStream()
- Upload() → UploadStream()
- Marker-based pagination → Pager-based pagination
- azblob.ResponseError → azcore.ResponseError

## Testing

All tests pass:
- ✅ Unit tests for metadata conversion
- ✅ Unit tests for helper functions (cleanKey)
- ✅ Interface implementation tests
- ✅ Build successful
- ✅ No compilation errors
- ✅ Integration tests available (require Azure credentials)

## Benefits

- ✅ Uses actively maintained SDK
- ✅ Better performance with modern API design
- ✅ Improved error handling
- ✅ Removes ~200 lines of custom upload code
- ✅ Reduces dependency count
- ✅ Better async/streaming support
- ✅ Future-proof against SDK deprecation

## Backward Compatibility

The changes are transparent to users:
- Same configuration parameters (account name, account key)
- Same functionality and behavior
- No changes to SeaweedFS API or user-facing features
- Existing Azure storage configurations continue to work

## Breaking Changes

None - this is an internal implementation change only.
