feat(helpdesk): promote ticket description to its own column in updates list

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.
