Location config dropdowns (Type, Path, etc.) live inside .task-item cards,
whose :hover applies transform: translateY(-2px). A transformed element
becomes the containing block for position:fixed descendants, so the popup —
previously a child of the card — was positioned with viewport coords against
the card instead of the viewport (wrong placement) and perturbed layout
(content shifted left).
Portal the popup to <body> on open and detach on close, so position:fixed is
always relative to the viewport regardless of any transformed/overflow
ancestor. flip-up styling moves onto the popup element and the topbar's wider
popup is carried via a class, since the popup no longer nests in the wrapper.
