sellvalue.lua: SetItemRef hook follows the same pattern questitem.lua
got earlier — replaces the local-Hook + _G.SetItemRef monkey-patch with
hooksecurefunc, drops the string.find link-parser, and reads itemID
directly from ItemRefTooltip:GetItem after the original populates the
tooltip. The OnShow path also moves from libtooltip:GetItemLink/GetItemID
to GameTooltip:HasItem/GetItem (libtooltip:GetItemCount stays — it's
populated by libtooltip's own SetBagItem hook and carries the stack
count, which GetItem doesn't return).
unusable.lua: the two post-hooks (pfUI.bag.UpdateSlot and
BankFrameItemButton_UpdateLock) are textbook hooksecurefunc cases —
both ran the original then did extra work, no conditional skip or
return-value tampering. The table form of hooksecurefunc handles
pfUI.bag.UpdateSlot cleanly.
