* TypeScript: fix optional debug calls and handleAction guards
The @microsoft/agents-hosting SDK's MsalTokenProvider automatically
appends `/.default` to all scope strings in its token acquisition
methods (acquireAccessTokenViaSecret, acquireAccessTokenViaFIC,
acquireAccessTokenViaWID, acquireTokenWithCertificate in
msalTokenProvider.ts). This is consistent SDK behavior, not a recent
change.
Our code was including `.default` in scope URLs, resulting in invalid
double suffixes like `https://graph.microsoft.com/.default/.default`.
This was confirmed to cause Graph API authentication errors. Removing
the `.default` suffix from our scope strings allows the SDK to append
it correctly, resolving the issue.
Before: we pass `.default` -> SDK appends -> double `.default` (broken)
After: we pass base URL -> SDK appends -> single `.default` (works)
