adventure: fix owner gear regression and drop em-dashes from equip copy

Show the public Gear panel whenever the owner's Equipment panel won't
render (no pushed Slots), so an owner whose detail predates ask 7 still
sees their standard gear instead of a blank. Replace em-dashes in the
equip feature's user-facing strings with plain commas.
