Fix how delegated votes are counted in the results (UI)

[ferranrego]

Currently, only 1 vote per delegate is being counted when a user with delegated votes participate in a poll.

However, this approach leads to a significantly lower reported voter participation, as its not counting all the votes

To address this, we should include all votes in the UI (Frame and Participant Turnout block). For example, if a delegate has 5 votes, each with a weight of 10, their participation should be recorded as 5 votes with a total weight of 50.

After looking into this problem, we realized that when a user delegates their votes, this user is taken off the census list, so the percentage of voters (turnout) is calculated correctly and will not affect the results.

[ferranrego]

• The census is always the entire list of holders/members of that community, and is the one used for the turnouts.
• We don't delete the users who delegated their votes from the census that is used to calculate the turnout.
• Each delegate should be counted as its vote + the delegated votes (and their respective weights).
