ui: restore ready_text.png splash sprite

ready.cc:75 loads /data/openpilot/selfdrive/clearpilot/theme/clearpilot/images/ready_text.png
to render the 'ready' text on the splash, but the asset never got copied
during the C++ UI port (b5a0b32). isNull() check meant it just silently drew
nothing. Copied verbatim from the broken tree.
