wren: improve scrollbar mouse navigation

Make ListView track clicks jump to the proportional viewport position
instead of consuming the click without moving. Shift its selection with
the viewport so the focused lightbar remains on the same screen row.

Treat wheel events over a scrollbar as page navigation in ListView, Help,
and LogView while retaining their existing item or line increments over content. Leave button drag handling unchanged so each control preserves
its current text-selection or thumb-drag behavior.

Document the mouse rules and add coverage for track clicks and page-wheel navigation across all three scrollbar consumers.
