Rewrite history page filters to act after event grouping

[adhityamamallan]

Summary

• Rewrite workflow-history to allow filtering only event groups, to avoid the (expensive) event grouping operation every time filters are applied.
• Modify existing filter functions to work with event groups
• Add unit test coverage for filtering event groups by type
• Misc:
  • Add fixtures for more types of event groups
  • Change Virtuoso scroll-to-event behaviour to automatically snap to a selected event instead of scrolling to it
  • Fix typo in fixture file name

Pull Request Overview

This PR refactors the history page filters to run on already-grouped events, improving performance by avoiding repeated grouping. It replaces event-level filters with group-level filters, adds new helper functions and tests for filtering by group type/status, and updates fixtures and scroll behavior.

• Apply filters after grouping (group-level filtering)
• Remove old event-level filter logic and associated types
• Introduce filterGroupsByGroupType and filterGroupsByGroupStatus helpers with unit tests

The useEventExpansionToggle hook now receives the unfiltered events array instead of filtered events/groups. This may cause toggles to include events that should be hidden by the active filters.

This is intentional; it's so that Expand All applies to events that are also being filtered out. Therefore, if the filter is removed, the events will show up again but in the expanded state.

[nitpick] Multiple scrollToIndex calls inline the string 'auto' for behavior. Consider extracting this into a constant or shared function to reduce duplication and ease future behavior changes.
