refactor: Use groupType-based filtering for Workflow History Group Category filter

[adhityamamallan]

Summary

• Create new config that maps from event group type to category
• Replace function-based filtering config for Event Group Category, and use the config map instead
• Move old function-based helper for calculating an event group's category from filtering logic, and reimplement it using the new map
• Reimplement the category filter to use getEventGroupCategory instead of doing so the other way around
• Rename "groupType" to "category" in timeline and navigation bar for consistency
• Rewrite the status filter to use a similar map-based approach instead of hardcoding the logic

Test plan

Added/updated unit tests + ran locally to sanity-check that filters still work as expected.

Pull request overview

This PR refactors the filtering logic for workflow history v2 by replacing function-based category filtering with a direct constant mapping approach. The change simplifies the code, improves type safety, and eliminates the need for runtime function evaluations when filtering event groups.

Changes:

• Introduced WORKFLOW_HISTORY_EVENT_GROUP_TYPE_TO_CATEGORY_MAP and WORKFLOW_HISTORY_EVENT_STATUS_TO_GROUP_STATUS_MAP constants for direct type-safe mappings
• Simplified filter-groups-by-category and filter-groups-by-status functions to use direct map lookups
• Removed deprecated get-event-group-filtering-type helper function and workflow-history-event-group-category-filters.config file
• Updated all components to use the new mapping directly instead of calling helper functions
• Renamed TimelineRow.groupType to TimelineRow.category for consistency
• Renamed NavigationBarEventsMenuItem.type to NavigationBarEventsMenuItem.category for consistency
