Add pose icon capture pipeline, icon scale, Esc/Tab opens overview in paint mode

- PoseIconStage: permanent editor capture pipeline (context menu 'Capture All Icons') — renders each entry at 4096x4096, alpha-crops, writes Icon_pose_*.png and wires sprites onto matching PlayerPose assets
- PlayerPose: new iconScale property (0.1-2), applied to the icon child in PoseMenu's radial layout
- OverviewMenu: paint-mode special-case removed — Esc/Tab opens the overview menu in every mode
