feat(labs): compact editable biomarker list with hide

Rebuild the biomarker manager as compact rows (name + unit inline,
reference range / panel on a muted sub-line) with a hide toggle, an
edit button, and a delete, replacing the one-card-per-marker layout.
Hidden markers collect in a separate restorable section. Filter hidden
markers out of the lab-entry picker, keeping the currently selected one
visible so an existing reading still resolves its label.

Touch targets meet the 44px mobile floor (size-11 sm:size-9).
