Enhance Poll List Dashboard with Filtering and Analytics

[Roubean1]

Enhance the existing poll list dashboard ( web/src/components/pollList.tsx) to provide advanced filtering capabilities and poll analytics to improve user experience and poll management.

Requirements

1. Channel-Based Filtering

• Filter by Channel: Add a dropdown/select component to filter polls by Slack channel
• Channel Search: Implement search functionality within the channel filter dropdown

2. People-Based Filtering

• Add ability to filter polls by poll creator/author
• Filter by Participants: Filter polls based on who has voted
• User Search: Implement user search with autocomplete functionality
• User Display: Show creator information and participant count for each poll

3. Poll Count Analytics

• Channel Statistics: Display poll count per channel in a summary view
• Visual Indicators: Use badges or counters to show poll quantities
• Sortable Counts: Allow sorting channels by poll count (ascending/descending)
• Time-based Counts: Show poll counts for different time periods (today, this week, this month)

4. Poll Status Analytics

• Active vs Closed Counters: Display counts of active and closed polls
• Status Indicators: Visual status badges for each poll (active/closed/draft)
• Filter by Status: Quick filter buttons for active, closed, and all polls
• Status Distribution: Show percentage breakdown of poll statuses

Technical Notes

• Consider implementing debounced search for performance
• Use React Query or SWR for efficient data fetching and caching
• Implement proper error handling for filter operations
• Add proper TypeScript types for all new interfaces
