feat: senior citizen interest rate fix for FD/RD accounts + CBS table renames

- Apply senior citizen rate override in FixedDepositAccount and RecurringDepositAccount
  getEffectiveInterestRateAsFraction() so maturity is calculated at correct rate (e.g. 7.5%)
  instead of chart slab rate on every event: submit, activate, posting, pre-closure, maturity
- Override getEffectiveInterestRateAsFractionAccrual() in both FD/RD to keep accrual
  consistent with maturity calculation — independent of DB nominalAnnualInterestRate value
- Add isSeniorCitizen and seniorCitizenInterestRate fields to SavingsAccount entity with
  JPA mapping and accessor methods; updateNominalAnnualInterestRate() helper added
- Extend DepositsApiConstants whitelist and SavingsAccountAssembler.applyCbsFields()
  to read and persist senior citizen fields from API request as final override step
- Add DepositAccountAssembler early-stage rate override for senior citizen accounts
- Liquibase migration 2015: add is_senior_citizen and senior_citizen_interest_rate columns
  to m_savings_account table
- Liquibase migration 0300: rename fd_base_interest_rate tables to CBS naming convention
- Update CBS copyright header in FdBaseInterestRateEffective and FdBaseInterestRateSlabHistory
