fix(ui): queue panel resize handle no longer blocked by main scroll hit-test

Browse Source 
The queue resizer overlaps the main column by a few pixels; treating
clientX <= mainRight as "main" suppressed grabs on that strip. Cap overlay
thumb horizontal slop at mainRight so it does not steal hits on the
resizer. Sidebar / other overlay thumbs stay out of scope via selector.
