Navigating from one panel to another (files list to a preview, a preview to another file) had no way back. The panel now keeps an in-memory stack of the panels it showed and renders a back arrow in the shared header. Browser history is not usable here: panel state lives in hash params written with replaceState.

Description
Going from the files list into a preview, or from one preview to another, left no way back. The panel now keeps an in-memory stack of what it showed and renders a back arrow in the shared header. Browser history can't serve here: panel state lives in hash params written with
replaceState, so no entries are pushed. The stack is capped at 50 entries and cleared when the panel closes.Tests
Provider tests cover the stack, walking back through several panels, no entry on reselect, and clearing on close.
Risk
Low. The arrow only shows when there is something to go back to.
