Combat: condition dropdown picker with tag chips

- System-aware condition list (5e PHB / pf2e) in src/lib/rules/conditions.ts
- Dropdown replaces free-text input; non-valued conditions add instantly,
  valued ones (Exhaustion, Frightened N, etc.) show a value field, plus Custom
- Already-applied conditions disabled in the list; chips remain click-to-remove
- New e2e covering preset + valued add and tag removal
