feat(investment): sell, redemption, write-off, GOI transfer and amortize screens

- Purchases are saved as Pending Settlement. Holdings show the status and
  a Settle button (from the settlement date), and the GL transaction id
  once settled.
- The transaction log shows "Not posted (pending settlement)" until a
  deal is settled, and dates the purchase on its settlement date.
- Broken-period interest is counted up to the settlement date.
- Accounting Preview title and the Holdings Settlement Date column
  reflect settlement-date posting.
