FINERACT-2197: Fix FEB_29_PERIOD_ONLY strategy for cross-year repayment periods

[pratikpatel-aurochs]

Description

isPeriodContainsFeb29 in ProgressiveEMICalculator only checked the repaymentPeriodFromDate's year for leap year. A repayment period spanning from a non-leap year into a leap year (e.g., Dec 1, 2023 → Mar 1, 2024) returned false even though Feb 29, 2024 falls
within the period.

This caused two downstream issues for FEB_29_PERIOD_ONLY strategy:

• numberOfDaysFeb29PeriodOnly returned 365 instead of 366
• partialPeriodCalculationNeeded was false, skipping the year-splitting interest calculation

Fix: Iterate all years the period spans and check each leap year's Feb 29 against the range.

Impact: Affects progressive loans using ACTUAL days-in-year + FEB_29_PERIOD_ONLY with non-monthly repayment frequencies (bi-monthly, quarterly) where a period crosses from a non-leap year past Feb 29 of the next leap year. Monthly repayments are not affected.
