feat(appearance): launch wallhaven-dl instead of the TinEye searchHEADmaster

The reverse image search never worked in practice: the clipboard-and-paste
route to TinEye was the only one left after scripted uploads hit bot and
consent walls, and it still left finding and replacing the file by hand.
wallhaven-dl, a separate app, does both the search for a larger copy and
general wallpaper search and download, so the button now launches it and
the TinEye code is removed rather than hidden.

The button is always shown, not only for a low-res staged image, since the
app is useful beyond upscaling. It launches through gtk-launch and the
app's desktop entry, which needs no ~/bin on quickshell's PATH and keeps the
app's taskbar icon, and closes the panel so the window does not open under
the overlay.

 Under the mock screens a note in the same colour says why, for the hovered

 `wallp` does the actual work, including running `udt-accent`, so the accent
 follows the new wallpaper exactly as it does from a terminal. This panel
