Three play-testing reports.
1. Buttons behind an open panel were still clickable. There are two
input paths and both leaked. GUI clicks: the research and formation
panels cannot block with mouse_filter = STOP, because their contents
are driven from raw _unhandled_input and a Control consuming touches
through the GUI system swallows them first - so the panels stay
transparent and IconButton now checks whether it is behind one, via a
"modal_menus" group. Raw input: a touch landing on the research panel
but missing a node was left unhandled, so it fell through to
GameController - which sits on the ROOT node and sees whatever its
children ignore - and moved the fleet or pinch-zoomed the world.
2. "Store ore here" looked dead. It was working: the confirmation was
overwritten one frame later by the per-frame status refresh added in
#16, so it flashed for a single frame. Craft-panel messages now
outlive a refresh (3s), and the button stays ENABLED with an empty
hold so pressing it can say why - a greyed button that cannot explain
itself is the same dead-button problem.
3. The mothership's description could overlap the button below it. The
description block was positioned from the TOP while the buttons were
anchored to the BOTTOM, so the gap between them was whatever the
screen height left over - overlapping at 1280 and separating at 960.
It is one bottom-anchored stack now, checked at both.
