Fixed EXT-6930(normal) - Edit Outfit: "Add wearables" panel layout is broken.

NOTE: this is a temporary fix, see EXT-6564(Fix wearable editing panels) for more info.
Fix info:
- Moved edit wearable button to place where it does not break widget paddings.
- Updated code that calculates button position.
- Sending button to front to ensure it is clickable and visible.

Not reviewed.
