fix(ui-lvgl): popups no longer shrink when their list is pulled past its end

LVGL 9.2.2 measures a SIZE_CONTENT box from its children as scrolled, so an
elastic pull past the end of a capped popup list shrank it by the overshoot,
again on every pull. lvgl_patches.py fixes calc_content_height in the
downloaded library (a build middleware for PlatformIO, called directly by the
sim's build_wasm.sh).

The five popups that each built the same panel now share popupOpen() (fit to
content / full height / under the status bar).
