Selecting an app now opens a detail window (name, state, description)
with Back / Install-Update-Reinstall / Delete, where delete needs
confirmation and refuses to remove AppStore itself. Install progress
replaces the button hints in that window instead of a full-screen status.
Catalog entries are kept as raw lines and expanded only for drawn rows,
and the catalog is released before net.wifiConnect() then rebuilt from
the SD cache, which is what caused OOM when bringing up Wi-Fi. Status
screens use REFRESH_FAST between updates rather than REFRESH_HALF.
