Failed Azure Credential errors not displayed to user without Debug Logging

MAPT currently fails to display critical Azure authentication errors to the user unless debug logging is explicitly enabled.

The output shows a generic success-like message (DEBU context initialized for mapt...) followed by a silent failure of DefaultAzureCredential due to an expired client secret (AADSTS7000222: The provided client secret keys for app '***' are expired.).

Impact: Users cannot diagnose the root cause of an apparent application failure without manually enabling verbose logging, leading to poor user experience and increased troubleshooting time.

Required Fix: MAPT should be updated to surface relevant, non-sensitive errors from the underlying Azure (like expired credentials or authorization failures) to the standard output or error stream, regardless of the debug log setting.

Example Log (Requires Debug Mode)
The following log snippet shows the critical error, which was only visible after enabling debug mode:

Start by tracing MAPT's Azure credential acquisition and the logging path used when DefaultAzureCredential fails. Reproduce an expired-credential failure with debug logging disabled; done when relevant, non-sensitive authentication errors are shown on standard output or error without enabling debug logging.
