feat: add support for proposals with pending results

[wa0x6e]

Summary

Closes: https://github.com/snapshot-labs/workflow/issues/332

This PR adds support for offchain proposals with pending results (when scores_state is not final)

Pending score happens for:

• proposal with privacy, when choices are being decrypted on proposal close
• proposal with overriding strategies, which recompute results on proposal close

How to test

On proposal with privacy

1. Go to http://localhost:8080/#/s:192022.eth/proposal/0xcf442aa4277322dd14715326541d43c9c9bd7bf143d3bebfc93ed685a45c2668/votes
2. It should display a message about results being finalized in place of the results (in the sidebar)
3. It should display a message in place of the choice in the votes list

On proposal without privacy

1. Go to http://localhost:8080/#/s:aave.eth/proposal/0x95a80ac25f97e0fc06528452e2c33d7cc179b801ddc4d8dd164964ce8e1d450e/votes
2. It should display a message about results being finalized in place of the results (in the sidebar)
3. The choice in the votes list should be the final choice

Note

We don't support when the proposal has scores_state as invalid state, since it's not handled on v1 either

Any idea why these proposal are stuck with results not finalized? Is just proposal with invalid score?

We should show the logo Shutter on proposals with Privacy

Proposals are stuck for various reasons:

• an issue from the proposal itself: fix: invalidate proposal score when out-of-range snapshot-sequencer#280
• an issue with webhook (we trigger the score finalization from webhook)

There's currently ~260 closed proposals with pending state. Will trigger the score finalization manually.

We should have a somewhere to ensure the finalization is triggered in case webhook is lost

Looks good to me, how do we trigger webhook? I visited your proposal on v1 to see how it's handled there and it looks like it triggered decryption.

Do we trigger it from the UI? If that's the case then we probably should bring back that trigger to new UI, otherwise we won't trigger it 🤔

Computation is triggered via webhook, on proposal close, everything is done on backend, no more trigger for that from the UI.

There's a few cases where finalization trigger are missed, as webhook are not retried on error, need to work on a solution to ensure all trigger is called.
