 - Corrected an off-by-one issue where selection previously stopped one row above the clicked item.
 - Added visual highlighting for all rows that are selected via checkmarks to clearly indicate active selection.

+### Fixed
+- Fixed an issue on the Run Checks page where the last row in a shift-selected range was visually highlighted but its checkbox was not checked.
+- Ensured checkbox state and row highlight state stay fully in sync for all rows in a shift multi-selection.
+- Corrected selection logic so every row within the calculated range is consistently selected and marked.
