Implement message preview feature for support tickets

- Added a new property `MessagePreview` to the `TicketSummaryDto` to display the truncated first message of a ticket. - Updated the `TicketMapping` class to retrieve the first message for each ticket and truncate it for preview purposes. - Modified the `SupportTicketList` and `AdminSupportPage` components to conditionally render the message preview in the ticket list, enhancing user experience by providing context at a glance.
