fix(hyprlua): columns layout breaks on fresh workspaces, wrap focus u/d

hypr-nav fell back to the raw "lua:columns" backend string on any
workspace that had never been explicitly switched via the menu (i.e.
every fresh workspace, since columns is the global default), which
didn't match the "columns" layout name it checks against — so focus/
move/resize silently took the generic dwindle-style path instead of
being forwarded to the custom layout. Strip the "lua:" prefix in the
fallback.

Also make focus/scroll u/d within a column wrap around instead of
stopping at the ends.
