T11 review caught that get_ticket was the one function without the *, marker
all other functions in the module use. One-line fix, no caller impact.

create_ticket, update_status (sets resolved_at on resolve), get_ticket,
list_tickets_for_account (status filter, account-scoped), promote_to_psa.
Used by L1 intake when account has no PSA integration configured.
