feat(hyprlua): size a fresh workspace's initial column count to monitor width

A workspace with no seeded/published column count used to always start
at a hardcoded 2, regardless of monitor size. Now it picks
floor(usable_width / 700), so ~700px per column — 1080p still lands on
2, wider monitors start with more instead of one cramped column.
