tools(re): walk the record pool embedded in the club-model owner

Records are 0x180 bytes starting at owner+0x162d8, below the embedded
manager subobject at owner+0x1f9d8. Walking that pool answers whether the
client ever builds a record for an item it was served, independently of
whether the record is filed into a collection.

Result on the live client with the kit selector open: 21 records exist -
18 squad players with category 1, plus one cardtype 10 and two cardtype 4
staff with category 0 - and no cardtype 7 record anywhere, despite two kit
items having been served three times in the same boot.
