* fix(app): make the sidebar resize handle usable by touch The drag handle was a 10px strip at `right: -5`, so half of it sat outside the sidebar's bounds. Web hit-testing does not clip to the parent box, but iOS `hitTest:` and Gesture Handler's Android traversal both do, leaving a ~5px target with no visible affordance — hover is the only cue, and hover never fires on native. Split the handle by input capability rather than by platform: a fine pointer keeps the hairline straddling the border, and touch gets a 24x88 grab target that sits fully inside the sidebar with a permanent grip. The pan gesture now requires horizontal intent and fails on vertical drift, so a finger on the grip still scrolls the list behind it. `useHasFinePointer` replaces the copy of the same media query that lived in the review surface.
