Adds a toggle switch in the summary bar to quickly hide non-GPS photos from the gallery grid. More discoverable than filter chips. - Toggle switch with clean CSS animation (sliding pill) - Renders inline in summary grid next to GPS/no-GPS counts - Overrides filter chips when active (GPS-only supremacy) - Persists across photo additions (DOM state, not reset) - Gallery, detail card, and upload functions all respect it
