Fix auto_flow row clear logic for variable-height thumbnails

The nested if/else suppressed sm-breakpoint clears after items 4, 8,
12... (multiples of 4 took the lg branch). Replace with three
independent checks — one per breakpoint — using Bootstrap 3
visible-*-block so each grid size gets its own clear on its own
row boundary.
