 - Implemented click interception before the browser toggles the checkbox state to prevent unintended full selection from the indeterminate state.
 - Added consistent keyboard behavior: pressing Space on the indeterminate header checkbox now also clears the selection.

-
-- Fixed the “Select all” checkbox behavior on the Run Checks page.
-- Resolved an issue where the checkbox remained in the indeterminate (`-`) state after clearing the selection.
-- Ensured that after clearing all selected rows, the “Select all” checkbox can again be used to select all rows normally.
-- Improved synchronization between individual row selection and the global “Select all” checkbox state.
