Improve Governance consensus rules

[JSKitty]

Abstract

This proposal fixes a handful of small areas where MPW deviated from PIVX Core's Governance consensus rules, those being:

• The 'Budget Fee' finalisation confirms: MPW now uses PIVX Core's rules for Mainnet and Testnet.
• The 'Budget Fee' confirmation time (24h rule), for this, we use IsEstablished from the getbudgetinfo results.
• • I would have preferred computing confirm time in-MPW to reduce RPC reliance, but it felt overkill for a single bool.
• Fixed how MN votes are computed, now MPW uses the exact same calculation without rounding, which stops Testnet 0 vote proposals from "Passing" due to Testnet's low MN count.

When a proposal falls under the '24h rule' (on Mainnet, it's 5m on Testnet) then the Governance Dashboard will signal this with a "Too Young" message, and will not allow it to pass or be funded.

Testing

To test this PR, it's suggested to attempt these user flows, or variations of these:

• Compare PIVX.org with MyPIVXWallet (this PR), ensure the Passing and Funding states 100% match.

If any errors are found, the PR works unexpectedly, or you have viable suggestions to improve the UX or functionality of the PR, let me know!
