Voting only with single-sided staked PSB NFTs

Currently, voting is allowed by unstaked PSB, single-sided staked PSB in SAR NFTs, and delegated PSB via the PSB contract.

To encourage community members to utilize SAR staking, we propose a governance switch to only allow single-sided staked PSB in SAR NFTs to vote.

This would mean 1 PSB staked in single-sided SAR NFTs = 1 vote.

Your voting power would include the number of PSB staked across all your single-sided staked NFTs.

If approved, the changes will be implemented for following governance proposals.
