feat: accounts list — active-only filter, date range & as-on-date search (backend)

- SearchParameters: added fromDate, toDate, asOnDate (LocalDate) fields with hasX() helpers
- SavingsAccountsApiResource: added status, fromDate, toDate, asOnDate query params
- SavingsAccountReadPlatformServiceImpl: resolveStatusEnum(), date filters on activatedon_date, default ORDER BY id DESC
- CurrentAccountsApiResource + service: same filters on ca.status_enum and ca.activatedon_date
- DepositAccountReadPlatformService (interface): new retrieveAllPaged overload with date/status params
- DepositAccountReadPlatformServiceImpl: resolveStatusEnum(), date filters, default ORDER BY id DESC for FD/RD
- FixedDepositAccountsApiResource + RecurringDepositAccountsApiResource: pass new params to service
