Remove the 25% side panel column: the header bar and game world view now
span the full window width, and the selection panel floats over the world
at its right edge, content-sized and shown only while something is
selected.
REQ-UI-PANEL-COLUMN is replaced by REQ-UI-SELECTION-PANEL, which defines
the panel's geometry, visibility, overlay, and input rules. The panel is
centered within the view height less its margins and the build button
bar's strip, so the bar never has to move out of its way. Rename the
"selected building panel" to "selection panel" throughout, since it has
long shown ships, stations, and debris too.
