fix(helpdesk): revert to PBI_LV_Tickets for team query, add error logging

PBI_FP_Tickets (FactPage) fails without a customer filter. Switch back
to PBI_LV_Tickets which works reliably unfiltered. Description and
Company_Contact_Name added to select — BC will return them if available,
otherwise they fall back to empty strings via existing null-coalescing.
Add console.error in JS catch to surface rendering errors.
