Replace free-form fractional HUD widget positioning with a 4x8 int grid (col/row/colSpan/rowSpan), reject drag/resize moves that would overlap another visible widget, and re-place a re-enabled metric into the next free grid slot instead of stacking it on an occupier. Drag/resize now track a local pixel offset during the gesture and only snap/commit once at gesture end. HUD widget text is wrapped in FittedBox(scaleDown) so it never overflows and stays centered at any grid size.
