cli: Add warning to full unbond as orchestrator

[moudi-network]

What does this pull request do? Explain your changes

This PR adds a CLI warning when an orchestrator attempts to unbond their entire stake. This prevents accidental deactivation of orchestrators by requiring explicit confirmation before proceeding with a full unbond.

Specific updates (required)

• Added a check in the unbond() function to detect when an orchestrator (self-delegated) is unbonding their full bonded amount
• Added a warning message explaining that full unbond will deactivate the orchestrator
• Added a y/n confirmation prompt to prevent accidental full unbonds

How did you test each of these updates (required)

Does this pull request close any open issues?

Seems OK to me, might be good for orchestrator-developers to get eyes on this too ... cc @ad-astra-video @eliteprox
