feat(deposits): RBI premature closure compliance, simplified to always use the contracted rate

Adds a Closure Reason to premature FD closure (Normal, Premature Extension,
Conversion to Another TD, Deceased Settlement, Nominee/Legal-Heir), persisted
as an RBI audit trail on m_deposit_account_term_and_preclosure. RBI-mandated
reasons auto-waive the pre-closure penalty regardless of the maker's own
checkbox; the maker can also waive it explicitly for any other reason.

Interest rate for a premature closure is always the deposit's own contracted
rate -- the same one its regular scheduled postings use throughout its life
-- rather than a slab re-lookup against the actual period held. An earlier
"actual-period vs contracted" toggle was built, tested, then deliberately
removed per explicit request: simpler, and avoids disagreeing with interest
the account was already accruing all along.

Also fixes a real bug found while testing this: a renewed FD term's premature-
closure interest was including the previous term's closing transaction a
second time (it's dated the same day the new term starts), understating the
first day's balance by the whole prior term's payout. Scoped the interest
calculation to transactions strictly after the current term's start date.

Known open issue: a renewed/auto-renewed account can still show a materially
wrong (sometimes negative) premature-closure interest figure in some cases
(seen on account 10, a QUARTERLY-posting auto-renewed FD) -- root cause not
yet confirmed; needs further investigation with debug instrumentation before
this is considered fully correct for every renewal shape.
