debug(framepool): add gated [QD] trace for FakeHide/FakeShow

Adds a print() block in _Qframe:FakeHide and _Qframe:FakeShow, gated by
_G.QuestieDebugPins. Dumps frame name, shown/hidden state, parent, and
anchor point. Used to diagnose why minimap pins reappear or fail to hide
after zone transitions or anchor re-registration.

Default state: GATE IS OFF. The block is a no-op unless the user
explicitly sets _G.QuestieDebugPins = true. Zero runtime cost in
production. All API calls defensive with tostring() and parent.GetName
fallbacks.
