Subject: [PATCH] feat: add "Usable" filter to auction house and query token
 item names

Add a "Usable" checkbox to the AH search UI that filters results to
items the player can actually equip/use (server-side filtering via the
usableOnly parameter in CMSG_AUCTION_LIST_ITEMS). Also ensure token
item names for extended costs are queried from the server via
ensureItemInfo() so they display properly instead of "Item#12345".
