Pull Request Overview

Adds health checks for Azure App Registration client secrets (and certificates) by implementing a new GetAzureHealth function, wiring it into the main health router, and providing fixtures and tests to validate healthy, expiring, and expired states.

• Implement GetAzureHealth with default and configurable expiry grace period
• Integrate Azure health into GetHealthByConfigType and allow overriding the grace period
• Add YAML fixtures and table-driven tests covering healthy, expiring, and expired client secrets

pkg/health/health_azure.go:16

• The variable azureClientSecretExpiry represents a grace period rather than an absolute expiry; consider renaming to azureClientSecretExpiryGracePeriod for clarity.

azureClientSecretExpiry = defaultAzureClientSecretExpiry

pkg/health/health_azure_test.go:54

• The certificate case (Azure::AppRegistration::Certificate) is handled in production code but not covered by tests; add a fixture and test case for certificate expiry/healthy states.
