FE 2 - Implement search, filter, and sort functionalities to the table

[notjackl3]

Add search, filtering, and sorting functionality to the volunteer tracking list.

Notes:

• This ticket is built on top of the existing volunteer table UI
• Debounce search input to avoid excessive API calls (100-300ms)
• Filters should be applied server-side or client-side depending on data size
• Ensure filter state is preserved appropriately
• Include a description of the ticket and the implementation in the PR (with screenshots showing search, filter, and sort in action!)

The goal is to:

• Implement search bar that filters results across all text fields
• Create "Filter" button that opens a filter dropdown/panel
• Add filter by "Current Role" dropdown with options fetched from API
• Add filter by "Cohort" dropdown with options fetched from API
• Show active filters as tags below the filter bar
• Create "Sort" button that allows sorting by any column (ascending/descending)
• Display "Filtered by: Current Role, Cohort" indicator when filters are active
• Ensure filters, search, and sort work together correctly
• Handle edge cases (no results found, clearing filters)
