[SC-06] Build governance UI — proposals and token-weighted voting on tokenized assets

[yusuftomilola]

Overview

The voting module (contracts/assetsup/src/voting.rs) provides governance over tokenized assets (proposals, token-weighted votes, thresholds). No UI exists.

What to Build

A Governance tab on tokenized assets (and/or a global /governance page listing proposals across assets the connected wallet holds tokens in):

1. Proposals list: title/description, proposer, status (active/passed/rejected/executed), deadline, live tally with a threshold progress bar
2. Create proposal: form per the contract's proposal entrypoint (wallet-signed, holders only)
3. Vote: for/against with the holder's token weight shown before signing; one-vote enforcement surfaced from the contract
4. Outcome: passed proposals show their execution state where the contract exposes it
5. Share voting/tally components with [SC-05]'s detokenization votes — build them once

Acceptance Criteria

• Full proposal lifecycle drivable from the UI on testnet
• Vote weight reflects actual token balance; non-holders cannot vote
• Tallies update after each vote and match contract state
• Deadlines and thresholds clearly visualized
