Add the option to view the list of voters for each choice in the webapp UI #139
Description
On the polls page, where the results are displayed, we need to add the list of voters for each option just below it. There should be a preview of the first 5 voters (or randomly selected ones) using their Farcaster pfp and, on the left side, a link that, when clicked, opens a modal showing the list of all voters for each option.
