Pull request overview

Fixes a filter-control + cookie interaction where the initial/deferred filter-control trigger could be treated as a user search and reset pagination state (e.g., pageNumber) after cookie restoration.

Changes:

• Adds an isInitial flag path from triggerSearch() → jQuery event data → createControls handlers → onColumnSearch() to distinguish initial render vs user-initiated searches.
• Updates initial filter-control triggering to call triggerSearch(true) on initial control creation.
• Adds Vitest coverage (including regression guards + behavioral simulation) for the #8246 scenario.
