Only show "Total" when the item is split across more than one location;
a single-location item made "Total" duplicate the one breakdown line
(e.g. "Equipped: 1 / Total: 1").
Route the Bags/Bank/Equipped/Total labels through the T translation table
and add the keys to every locale file, using the Blizzard GlobalStrings as
the reference for each localized term.
pfUI's Lua hooksecurefunc lived in pfUI.env and shadowed ClassicAPI's C
global for all pfUI code. Replace it with a thin pfUI.hooksecurefunc shim
that keeps the missing-target no-op our call sites rely on (ClassicAPI
errors on a nil target) and delegates the actual hook to _G.hooksecurefunc.
Migrated all 70 internal call sites (modules/libs/skins) to
pfUI.hooksecurefunc; bare hooksecurefunc now resolves to ClassicAPI's C
version everywhere. Dropped the unused prepend path and the orphaned
pfUI.hooks table.
