Age column on the workbench (days since opened); a still-open ticket aged past
ticket.sla_days (dated setting, default 7) shows red with a warning. New 'Overdue'
filter chip with an honest server-side count (still-open AND opened on/before the
SLA cutoff). Each row gains a 'Bill' action that opens New Document with the client
pre-selected (/documents/new?client=<id>) — the light ticket->invoice path, staff
add the lines. Kept deliberately un-bulky: no kanban, reuses the existing table.
Test locks the overdue filter + count. typecheck + full suite (403) green.
