The ticket description was only visible as a tooltip on the ticket number
link — easy to miss and not searchable by eye when scanning the list.
Move it to a dedicated "Description" column right after "Ticket".
- helpdesk-updates-index.js: new column between Ticket and Ticket status,
using the shared `.app-cell-note` class for ellipsis + title fallback
on long descriptions. Drop the now-redundant data-tooltip on the
ticket link. mapData gets one extra positional entry.
- updates/index(default).phtml: add ticketDescription label to
pageConfig. i18n key "Description" already exists in both core and
helpdesk dictionaries, no new strings required.
