<issue_title>Admin Center: Publish wizard shows "Publish failed" UI error despite agent being successfully published via a365 publish CLI</issue_title>
<issue_description>### Description

After successfully running a365 publish (CLI exits with success) and configuring the agent blueprint in the Teams Developer Portal, the M365 Admin Center publish wizard (admin.cloud.microsoft) consistently shows:

"We couldn't publish your agent agentframework Blueprint. Please try again."
However, the agent is actually published — it appears in the Agents → Requests tab with status Pending review and shows Copilot + Teams as supported channels. The wizard error is a false negative caused by CSP violations in the browser console:
Uncaught (in promise) Error: Publish command did not complete successfully
Connecting to '' violates Content Security Policy directive: connect-src

Link : https://github.com/microsoft/Agent365-Samples/tree/main/python/agent-framework/sample-agent

Expected behavior

The publish wizard should show success after a365 publish completes and the Teams Developer Portal is configured.

SDK Version

a365 v1.1.109.19759

Language/Runtime

Python 3.13.12

OS

Windows 11

How to Reproduce

1. Run a365 publish → CLI succeeds
2. Configure agent blueprint at https://dev.teams.microsoft.com/tools/agent-blueprint//configuration (Agent Type: Bot Based, Bot ID: )
3. Go to M365 Admin Center → Agents → Publish new agent
4. Select users → Apply policy → Review and finish → click Publish
5. Wizard shows "Publish failed" with CSP errors in browser console

Output

Actual: Wizard shows publish failure. Browser console shows multiple CSP connect-src violations blocking network requests from admin.cloud.microsoft.

Comments on the Issue (you are @copilot in this section)

@biswapm @smita-MSFT, Could you please cross check these configs and confirm.

Does the user have the right admin role?
Global Admin, or Teams Administrator + App Catalog Admin

Tenant-level app policies

Go to: Teams Admin Center → Teams apps → Permission policies
Check if custom/LOB apps are allowed for the tenant
If blocked at tenant level, the wizard may fail silently

Integrated Apps settings

Go to: Admin Center → Settings → Integrated apps
Check if the toggle for "Allow users to install preview features" or third-party/custom apps is enabled</comment_new>
