fix(helpdesk): use auto table layout with max-width:0 ellipsis pattern

Fix missing closing brace in CSS. Use width:100% + max-width:0 on
description column for consistent ellipsis across all agent tables.
Narrow columns (ticket no, customer, date) use white-space:nowrap to
keep natural width. No fixed percentages — fully responsive.
