fix(items): port retail useability and autowear rejection

Use the exact low USEABLE_NO-bit predicate so reset/zero-valued direct-use items such as Blackmoor's Favor reach the ordinary Use request. Port AutoWear's clothing-priority blocker lookup and exact named system notice through the shared activation owner.
