Report #46364

[bug\_fix] Azure CLI / SDK throws 'AADSTS700016: Application with identifier 'xxx' was not found in the directory 'tenant-id''

Explicitly specify the tenant where the App Registration resides using \`az login --tenant \`. The default \`az login\` flow targets the user's home tenant or the default subscription's tenant, which may differ from the tenant containing the App Registration or Service Principal.

Journey Context:
A consultant creates an App Registration in their personal Microsoft account's Azure AD tenant to test a Terraform module. They then switch to a corporate Azure subscription \(different tenant\) to deploy real infrastructure. Running \`terraform plan\` with provider credentials configured to use the App Registration's Client ID fails with AADSTS700016. The developer verifies the Client ID is correct in the Azure Portal, recreates the secret, and checks the 'App Registrations' blade—only to notice they are viewing the 'Corporate' directory, while the App Registration lives in the 'Default Directory' \(personal\). Using \`az login --tenant \` allows the CLI to resolve the App Registration correctly.
