Add CIP-179 survey support to governance voting

[Cerkoryn]

Summary

Adds optional CIP-179 v5 support to the governance scripts.

When a governance action links a public CIP-179 survey, the voting flow can:

• Detect and validate the survey link in the action metadata.
• Interactively collect survey answers.
• Create CIP-179 response metadata using the reusable cip-179 NPM package.
• Submit the survey response and governance vote in the same transaction.
• Support the standard CIP-179 question types.
• Reject conflicting metadata label 17 inputs.
• Validate linked action metadata against the current deposit and return address.

Existing voting behavior is unchanged for actions without a CIP-179 survey. The optional survey flow requires Node.js 20+ and cip-179@0.2.0.

Testing

This PR was made with the assistance of GPT 5.6 Sol High, but I personally tested end to end on Preview using a CIP-179 survey linked to an Info Action. The governance vote and survey response were successfully submitted together and indexed on-chain.

Note that this particular survey from @mpizenberg's tool was intentionally limited to a MAXIMUM of 10 answers, which is what I was testing when I inputted numbers 1-11 to violate that constraint.

It isn't exactly clear in the script/screenshot why that constraint was violated, but I could probably just put that in the survey question text next time. I.e....
