Fixed three issues identified by Gemini Code Assist:
1. HIGH: ReadFile now uses blob.CountToEnd when size is 0
- Old SDK: size=0 meant "read to end"
- New SDK: size=0 means "read 0 bytes"
- Fix: Use blob.CountToEnd (-1) to read entire blob from offset
2. MEDIUM: Use to.Ptr() instead of slice trick for DeleteSnapshots
- Replaced &[]Type{value}[0] with to.Ptr(value)
- Cleaner, more idiomatic Azure SDK pattern
- Applied to both azure_storage_client.go and azure_sink.go
3. Added missing imports:
- github.com/Azure/azure-sdk-for-go/sdk/azcore/to
These changes improve code clarity and correctness while following
Azure SDK best practices.
