fix(balance): disambiguate address drag — edge to reorder, centre to transfer

Browse Source 
The address list supported two drag gestures that collided: dragging a row onto another
transferred funds, dragging into a gap reordered. Since rows are contiguous, a reorder-drag was
almost always over another row, so it triggered a fund transfer instead of reordering.

Disambiguate by WHERE on the target row the drag is released (user's suggestion): the top/bottom
~30% edge bands = reorder (an insertion line is shown), the centre = transfer (the row highlights).
A zero-balance row or an off-row drop always reorders. Tooltip and i18n hint updated to match.
