Subject: [PATCH] refactor: collapse duplicate cn helpers into canonical
 lib/utils/cn.ts (Closes #1421)

Collapse the three identical Tailwind classnames helpers into a single
canonical implementation in lib/utils/cn.ts. lib/utils.ts and
lib/utils/index.ts now re-export from it instead of duplicating the
same twMerge(clsx(...)) logic.

Runtime behavior is unchanged; all cn-related tests pass.
