test(studio): import commitGsapPositionFromDrag from its actual module

The function was split out into gsapDragPositionCommit.ts in #1605, but
the test kept importing it from ./gsapDragCommit, which no longer exports
it — yielding `is not a function` at runtime. Import from the correct
module to match the production import in gsapRuntimeBridge.ts.
