   ### SUMMARY
   
     This PR adds **server-side filtering** for AG Grid Table V2, allowing 
users to filter large datasets efficiently directly from column headers.
   
     **What it does:**
     Currently, when server pagination is enabled, AG Grid column filters only 
work on the current page's data (e.g., filtering 50 rows instead of the full 
100,000 rows in the
     database). This PR changes that by converting AG Grid filter conditions 
into SQL queries that execute on the backend.
   
     **Key Points:**
     - Column filters now work across the **entire dataset**, not just the 
current page
     - Supports all common filter types: text (contains, equals, starts with), 
numbers (greater than, less than, ranges), dates, and blank/not blank checks
     - Handles complex conditions with AND/OR logic (e.g., "state equals CA OR 
NY")
     - Automatically separates dimension filters (→ WHERE clause) from metric 
filters (→ HAVING clause) for optimal SQL performance
     - Works in Parity with the Permalink feature and doesn't break Chart State
     - UX enhancement: filter popover auto-reopens after server refresh so 
users don't lose their place
