fix(layer-shell): resolve output layer container by WOutput

[zzxyb]

Use the underlying WOutput when resolving an output layer surface container from an Output wrapper. Keep both lookup overloads on the same identity so containers can be found reliably.

Reviewer's Guide

Layer-shell output surface container resolution now unwraps Output objects and uses the underlying WOutput for lookup, keeping both overloads consistent and ensuring containers are found by the identity they store.

Unifies output-layer container lookup around the underlying WOutput identity.	Delegates Output-wrapper lookup to the existing WOutput overload. Removes the separate container iteration and wrapper-pointer comparison path. Preserves a single identity-based lookup path for reliable container resolution.	src/core/layersurfacecontainer.cpp
