feat(history): drop the shared gallery's Linked images caption (D47 ruling)

The concept's "Shared gallery" heading is the gallery's only heading: the
embedded collection's "Linked images" heading and "N loaded · N linked
images" count repeated it. mountImages gains caption: false and a
focusTarget; only the history page's shared gallery passes them, so the
Images page and the All images and Repeat run dialogs keep their caption.
The layout row and the selected-image side panel stay (TESTING.md D47).
