## PR-Codex overview
This PR focuses on optimizing the calculation of voting results in the
`WeightedVoteResults` and `Vote` components by replacing manual
accumulation logic with utility functions from `lodash`, enhancing code
readability and maintainability.

### Detailed summary
- In `WeightedVoteResults.tsx`, replaced manual reduction of
`choicesVotes` with `_mergeWith` from `lodash`.
- In `Vote.tsx`, replaced manual construction of `newData` with
`fromPairs` from `lodash` for cleaner code.
