cherry-pick: set Azure login status to signed in after token retrieval (PR #15958 → dev)

[Copilot]

After a successful Azure login, AzureAccountManager.currentStatus was not being updated to loggedIn and listeners were not notified, leaving the extension UI and dependent features in a stale unauthenticated state.

Changes

• azureLogin.ts: After building the TokenCredential on successful login, immediately set AzureAccountManager.currentStatus = loggedIn and call void this.notifyStatus() before returning the credential.

// packages/vscode-extension/src/commonlib/azureLogin.ts
const credential: TokenCredential = { ... };
AzureAccountManager.currentStatus = loggedIn;  // ← added
void this.notifyStatus();                        // ← added

return credential;

Notes

Both changes from PR #15958 were already present in dev:

• The azureLogin.ts fix (lines 174–175)
• Version is already at 6.10.0, ahead of the 6.10.0-rc.0 bump that was release-branch-specific

No code modifications were required; this PR confirms the cherry-pick is complete.
