Merge pull request 'fix(ui): landscape board zoom/pan + rack tile rendering + mobile block label' (#141) from fix/landscape-board-ui into development

Follow-up to the contour review: with the rack now exactly seven fixed-size slots in the
narrow landscape panel, the 56px confirm button (sized for the roomy portrait rack) was
wider than the single slot a staged tile frees, so it overlapped the now-rightmost tile.
Match the button width to one landscape tile slot, so it sits inside the freed slot with
its right edge level with the rack's right edge — the mirror of the first tile's left edge.
