Subject: [PATCH] Rename UI to LED Editor and improve mobile editor layout

Use "LED Editor" in page titles and the home heading. On narrow
viewports, make the file tree an off-canvas drawer with backdrop,
hamburger toggle, Escape to close, and auto-close after opening a
file. Add safe-area and tap-target tweaks, cache-bust static assets.
