Pull request overview

This PR migrates the Azure Backup tool implementation to the newer command/options design where option registration and binding are driven by [Option] attributes (and subscription resolution is provided via ISubscriptionResolver), updating both production commands and unit tests accordingly.

Changes:

• Refactors Azure Backup commands to use the SubscriptionCommand<TOptions, TResult> / BaseAzureBackupCommand<TOptions, TResult> pattern and ValidateOptions(...) for validation.
• Migrates many Azure Backup options POCOs from JsonPropertyName-based binding to [Option] attribute metadata (including introducing VaultGetOptions).
• Updates Azure Backup unit tests to the newer command test base and adjusts DI setup accordingly.
