Add -HubName parameter to New-FinOpsTestData and Remove-FinOpsTestData via Get-FinOpsHub

[FallenHoot]

Summary

Add a -HubName parameter to both New-FinOpsTestData and Remove-FinOpsTestData that uses Get-FinOpsHub to automatically resolve hub infrastructure details (storage account, ADX cluster URI, container name, etc.).

Motivation

Currently users must manually specify -StorageAccountName, -AdxClusterUri, and -ContainerName separately. A single -HubName parameter would simplify the experience by looking up all hub resources automatically.

Proposed changes

• Add -HubName parameter to both commands
• Use Get-FinOpsHub internally to resolve storage account name, container name, ADX cluster URI, and database name
• Keep the individual parameters available for non-hub scenarios or overrides
• Add -HubName to the same parameter set or a dedicated parameter set

Context

Deferred from PR #2006 (New-FinOpsTestData and Remove-FinOpsTestData).
