Quat: opening Modes / Menu showed a solid dark-purple block in the
top-right with no readable content. Cause: the auto-fade system on
the top-level action bar was fading the popover rows too — they
share the `ActionButton` marker so `paint_action_buttons` can still
paint hover/press, but `apply_action_fade` matched the same marker
and dropped their alpha to whatever the cursor-position-based
fade happened to be (typically 0 because the cursor was inside the
opened popover, well below the top reveal zone). The popover
container stayed at full opacity (its background is `BG_ELEVATED`,
not driven by the fade), so what the player saw was the empty
rounded box with no labels.
Fix: new `PopoverRow` marker on the rows in `spawn_modes_popover`
and `spawn_menu_popover` (both share the same row-spawn shape).
`apply_action_fade` excludes `PopoverRow` via `Without<PopoverRow>`.
Hover / press paint still applies — the popover rows just opt out
of the cursor-position auto-fade since they only render when the
player has explicitly opened the dropdown.
