Whether the pill is currently lit (status active, or trauma present).
For a toggleable pill, the registered status-effect id (e.g. Foundry's
stun); for an indicator, the affliction subtype (auralshock/fatigue).
Tooltip label.
true → clicking the pill toggles the corresponding ActiveEffect status;
false → a read-only indicator lit from an active trauma subtype
(Aural-Shock / Fatigue), which are modeled as traumas rather than
toggleable statuses (#306).
A header status pill: its id, labels, active state, and how it is driven.
