feat(NexusViewer): add pool manager NXM locked for MV timestamp

[mixplore]

Description

Alternative for UI multicall https://github.com/NexusMutual/frontend-next/pull/1049 to support https://github.com/NexusMutual/frontend-next/issues/1044.

The advantage of this approach would be saving an on chain call on the UI, the disadvantage being this implies a smart contract deployment + not sure about how computationally heavy the added logic is. The UI approach is faster in terms of going live with the fix, but I don't think this is an urgent issue so we can decide based on the other criteria.

• getClaimableNXM call should return stakingPoolManagerIsNXMLockedForMV in the result

OR

• on local node: HARDHAT_NETWORK=localhost node scripts/get-claimable-nxm.js
