feat(savings,cashier): maker-checker cash closure with vouchers and rounding

Closing a savings account paid real cash out of a teller's drawer in one
click, with no maker-checker, no cash-position tracking, and no way to hand
over a paisa balance (no paisa coins circulate, and the denomination writer
demands an exact match). This adds a Clerk -> Manager -> Cashier flow for
Cash closures, modelled on the existing Clerk Withdrawal Request.

New ClerkClosureRequestApiResource:
 - submit: Cash only, token required, guards ACTIVE status and open requests
 - approve: runs Fineract's own close command (pro-rata interest and the real
   GL withdrawal post here, atomically), reads the posted transaction back,
   rounds the payout to whole rupees and posts the difference to a new
   Round Off Account. A nil-balance closure goes straight to CLOSED rather
   than parking forever in a cashier queue with no cash to hand over.
 - disburse: cashier records the denomination breakdown against the rounded
   figure and the account closes
 - preview: dry-runs the very same interest posting close() performs, inside
   a REQUIRES_NEW transaction that is rolled back, so the figure shown to the
   clerk matches the real payout to the paisa. Reading the stored accrual
   instead gave a days-stale number, and CALCULATEINTEREST is not equivalent:
   it uses MathContext(15) and no postInterestOnDate, where close() uses
   MathContext(10) and feeds the closing date in as a posting-period
   boundary, which changes how many per-period roundings happen.

Vouchers: close() reaches handleWithdrawal directly rather than through the
withdrawal command handler, so the handler's own raiseSavingsVoucher never
ran and a closure paid cash out with nothing in the voucher register. One is
now raised at disbursement -- when the cash actually crosses the counter, in
the cashier's name -- with three lines that match the posted GL exactly:
Dr Savings Control + Dr Round Off = Cr Cash.

Cash direction: the rounding adjustment debited Cash where cash leaving the
drawer is a credit, leaving the cash GL disagreeing with what was physically
handed over. Both legs corrected.

Dates: closure_date, closedOnDate, the preview and the rounding entry now all
use the CBS business date, so preview and approval cannot land on different
days across a day roll.

Day Book: closures were absent entirely (it reads the request registers, not
m_voucher). Added as a fourth register, restricted to CLOSED rows and dated
on disbursed_at, since a closure only becomes a cash-book event at hand-over.
Its terminal status CLOSED was also missing from the totals gate, so a
completed closure moved real money out without appearing in the DR total.
