[ARO-1542] Implement Azure SDK clients in MIMO Actuator

[hawkowl]

Which issue this PR addresses:

Part of ARO-1542

What this PR does / why we need it:

Implements the ability for MIMO tasks to use Azure clients through a single source. Clients are only generated when they are used.

Test plan for issue:

This code is currently unused but will be tested by parts of ARO-1542 and ARO-23471.

Is there any documentation that needs to be updated for this PR?

Existing documentation covers how to access items on the TaskContext.

How do you know this will function as expected in production?

Pull request overview

Adds Azure Track 2 SDK client access to the MIMO Actuator task context so tasks can lazily obtain Azure clients from a single place, and updates actuator plumbing/tests to include subscription context.

Changes:

• Extend mimo.TaskContext to expose Azure Track 2 SDK client getters (network/compute/ACR) and wire lazy client creation into the actuator task context.
• Plumb SubscriptionDocument access through the actuator/service so tenant-aware credentials can be created per cluster subscription.
• Update MIMO step/actuator tests and fake test contexts to use the new task context shape.
