Extend xWALLET staking for another year

Per our whitepaper, the first year of xWALLET staking is additionally incentivized (on top of fee buybacks) with a 4% of the total WALLET supply. This period ended in early February.

We propose that we extend the staking incentive with an additional 4% (of the total supply) for the next year, due to success of the staking intiiative so far - more than 50% of the circulating WALLET supply is currently staked. The additional 4% will come out of the DAO allocation and only amount to approximately 8% additional issuance, which won't go into circulation as it's distributed in staking rewards which are locked by default.

We are also introducing an alternative voting option: extend the staking with a total of 3% of the total supply distributed over the next year, which will amount to approximately 6% additional issuance.
