feat(investment): Interest Entry screen with coupon and provision schedule

Replace the dummy interest calculation tab with the real Interest Entry:
pick Type / Script / Deal No and Retrieve the holding's schedule from
the backend - every half-yearly coupon and every 31 Mar / 30 Sep closing
provision up to maturity, with days (30/360), gross interest, amount
already booked, net income and the Dr/Cr entry per line. Display only;
nothing is posted to GL yet.
