feat: add Copayment and Adjustment columns to payments table

- Added copayment and adjustment fields (Decimal, default 0) to Payment
  model in schema and directly to DB via ALTER TABLE
- Added PATCH /api/payments/:id/copayment and /adjustment routes
- Added inline-editable Copayment and Adjustment columns after MH Paid
  with same click-to-edit format; Copayment in blue, Adjustment in orange
