Adds a control-bar toggle (next to the Add Keyframe diamond) that, when off, makes a manual drag/resize/rotate/panel edit on an already-keyframed element shift the whole tween by the edit's delta instead of inserting or updating a keyframe at the playhead. The animation's shape is preserved, just moved. Wired into every path that can auto-record a keyframe: - canvas drag-to-move (tryGsapDragIntercept, reuses the existing Alt-drag "shift whole path" behavior) - canvas resize/rotate (tryGsapResizeIntercept, tryGsapRotationIntercept) - design-panel property edits (useAnimatedPropertyCommit) - motion-path keyframe-node dragging (MotionPathOverlay), the path a plain click-drag on a keyframed element's canvas shape actually takes, since the element renders exactly at its current keyframe's position The shared shift helper reuses synthesizeFlatTweenKeyframes for materializing a flat tween instead of hand-rolling it, and lives in its own file (gsapWholePropertyOffsetCommit.ts) to keep gsapDragCommit.ts under the 600-line cap, mirroring the existing gsapDragPositionCommit.ts split. Fixes #1808
