fix(statements): owner assignment dropdown, fix Wise CC false positive, remove amount label

- Add owner <select> dropdown per row using useUpdateStatement + useParticipants
- Detect CC by statement_type.includes('card') instead of credit_limit/payment_due_date
  (Wise multi-currency account had payment_due_date set but is not a CC)
- Amount: remove 'due'/'balance' label; color green for positive bank balances, red for CC/overdraft
- Add statement_type to StatementRow type
