The AzureDevOpsClient shared library already supports MI auth via ManagedIdentityClientId. This change is config-only: - settings.json: Remove [vault(dn-bot-dnceng-workitems-rw)] from AzureDevOps:dnceng - settings.Production.json: Add AzureDevOps:dnceng:ManagedIdentityClientId (d2580e46-...) - settings.Staging.json: Add AzureDevOps:dnceng:ManagedIdentityClientId (e9d81917-...) - dotneteng-status-secrets.yaml: Remove dn-bot-dnceng-workitems-rw vault entry The AzureDevOpsClient constructor already: 1. Prefers AccessToken (PAT) if present 2. Falls back to ManagedIdentityCredential if ManagedIdentityClientId is set 3. Uses the AzDO resource scope (499b84ac-.../default) for bearer tokens

1. Remove leftover comment from dotneteng-status-secrets.yaml (garath) 2. Replace wrong helix-cluster MI client IDs with UseManagedIdentity flag - Production and Staging settings now use 'UseManagedIdentity: true' - System-assigned MIs don't need a client ID (garath) 3. Add UseManagedIdentity bool to AzureDevOpsClientOptions - When true without ManagedIdentityClientId: system-assigned MI - When true with ManagedIdentityClientId: user-assigned MI 4. Split bearer auth test into user-assigned and system-assigned cases 5. Remove placeholder client IDs from post-deployment tests

Summary
Migrate the \dn-bot-dnceng-workitems-rw\ PAT (work_write scope, dnceng org) to Managed Identity in DotNet.Status.Web. The \AzureDevOpsClient\ shared library already supports MI auth via \ManagedIdentityClientId\ — this is a config-only change.

How it works
The \AzureDevOpsClient\ constructor (in src/Telemetry/AzureDevOpsClient/) already has MI support:
By removing the vault reference and adding per-env MI client IDs, the client will automatically use MI auth in staging/production.
