feat(investment): interest schedule API for Interest Entry

Add GET /v1/investment/purchases/{id}/interest-schedule. For a holding it
lists every half-yearly coupon and every 31 Mar / 30 Sep closing provision
from purchase to maturity, worked out on the face value still held:
provision = interest earned since the last coupon (30/360), and the coupon
clears what is already booked (purchased accrued interest or the earlier
provision). Lines up to the as-on date are marked due. Calculation only;
nothing is posted.

The day-count and interest arithmetic move into InvestmentInterestCalculator,
shared with Purchase Entry, and are covered by unit tests using Jitendra
Sir's worked example. Duplicate-code errors on the masters now keep the
original exception as the cause.

-    <!-- Converts manually-applied Configure Maker Checker Tasks changes into a repeatable migration.
-         During Admin -> Organization and Admin -> System testing, can_maker_checker was switched on
-         (via System -> Configure Maker Checker Tasks) for the 28 permissions below, directly in the
-         dev database - none of that was ever captured by a migration, so a fresh/other environment
-         restored from this changelog history would come up with every one of them still at its
-         originally-seeded false value. Every code here was independently confirmed, via read-only
-         inspection of both its origin changeset and the live database, to be seeded can_maker_checker
-         = false and currently true in the running dev DB with no existing changeset already covering
-         the flip (the one precedent for this pattern, DELETE_OFFICE, was flipped by changeset
-         0538_enable_maker_checker_for_delete_office and is deliberately left untouched here).
-
-         This changeset only ever moves can_maker_checker from false to true for these exact codes -
-         entity_name, action_name, grouping and every other column are left exactly as their origin
-         changeset defined them (including the pre-existing DELETE_ACCOUNTNUMBERFORMAT entity_name
-         drift, which is out of scope for this change and is not corrected here). No _CHECKER row is
-         touched: those already exist for every code below (added earlier by 0583/0586, or by base
-         Fineract for the stock codes), and can_maker_checker is not a column on a _CHECKER row.
-
-         Grouped by the screen each permission belongs to:
-           - Currency Configuration:            UPDATE_CURRENCY
-           - Manage Funds:                      CREATE_FUND
-           - Working Days:                      UPDATE_WORKINGDAYS

-           - Sponsor Banks:                     CREATE_SPONSORBANK, UPDATE_SPONSORBANK
-           - Branch Profile:                    UPDATE_BRANCHPROFILE

-           - UPDATE_PERMISSION, UPDATE_CONFIGURATION (the Configure Maker Checker Tasks self-lockout
