feat(dds): DDS product creation in tabs with an Accounting tab

- DDS Product Creation split into Details / Interest & Maturity /
  Premature Closure / Accounting tabs, like the savings product
- Accounting tab picks Customer Deposits (liability), Interest Expense
  and Agent Commission Expense (expense) GLs; product view shows them
- Approval review shows the product's GLs, old -> new on edits
- Agent master no longer reads the removed dds-deposit-product setting
