SV UI: add Submitted By column to governance tables (#3691)

[puneetfinoa]

Fixes #3691

Summary

• Add a Submitted by column to the redesigned governance listing UIs: Action Required, Inflight Votes, and Vote History
• Resolve VoteRequest requester SV names to party IDs and show truncated, copyable identifiers (no You badge)
• Align proposal-type cell layout with Figma (title + description stacked)
• Update unit tests to use shared mock party/contract IDs and cover the new column
