Add PF2e persistent damage condition tags

Persistent damage displayed as compact tags with damage type icon and
formula (e.g., Flame + "2d6"). Supports fire, bleed, acid, cold,
electricity, poison, and mental types. One instance per type, added via
sub-picker in the condition picker. PF2e only, persists across reload.
