Pull request overview

This PR syncs develop into main for the v1.24.0 release state, primarily to align main with the updated Connect-HaloAPI Key Vault unit tests (managed identity switch + Key Vault secret name/value behavior) so release history reflects a passing test baseline.

Changes:

• Update Connect-HaloAPI unit tests to use -UseManagedIdentity (instead of the prior -Identity argument pattern).
• Update Key Vault secret naming in tests from underscore-delimited to hyphen-delimited (e.g., halo-URL).
• Update Key Vault secret mock returns to match Get-AzKeyVaultSecret -AsPlainText behavior (plain text values).
