fix(useVotes): skip getPastVotes when snapshot is still in the future

Viewing a freshly created proposal during its voting-delay window made
the governor's proposalSnapshot() return a timestamp greater than
clock(), which caused getPastVotes() to revert with ERC5805FutureLookup.
Detect that case at mount and fall back to getVotes(), so the UI shows
the signer's current voting power as a preview until the snapshot
actually elapses.
