Fix widget layout clipping and add comprehensive widget previews

- Fix LargeVotingView mood icons getting clipped at edges by using
  flexible HStack spacing with maxWidth: .infinity
- Fix VotingView medium layout with smaller icons and even distribution
- Add comprehensive #Preview macros for all widget states:
  - Vote widget: small/medium, voted/not voted, all mood states
  - Timeline widget: small/medium/large with various data states
- Reduce icon sizes and padding to fit within widget bounds
- Update accessibility labels and hints across views
