Set min-width for lane wrappers in MultiStackView

- Modified MultiStackView.svelte to add a minimum width style for lane wrapper elements representing each stack lane.
- Introduced a new constant laneWraperMinWidth calculated from laneWidths array or 0 as default.
- Applied the min-width style binding to the div with class 'reorderable-stack' to ensure proper UI layout and prevent collapse of the lane wrapper.
This change addresses a visual layout issue in the multi-stack view component.
