## Review Fixes
- Paid late-fee deduction now counts only `PaymentAllocationStatusEnum.APPLIED` late-fee payment details, so reversed positive details are not deducted again.
- Paid late-fee deduction excludes original `APPLIED` late-fee details that have a `REVERSED` detail referencing them through `relatedDetailId`.
- The daily recalculation batch now selects unpaid charges with non-null `lateFeeBeginDate`, avoiding repeated starvation behind historical rows that cannot be recalculated.
- `script/xxl-job-init.sql` registers handler `lateFeeDailyRecalculation` for business-server with cron `0 30 3 * * ?`.
- `LateFeeRecalculationServiceTest` includes a defensive scenario where a reversed late-fee detail is returned by the mapper and ignored by aggregation.
- The daily recalculation job now uses keyset pagination (`id > lastId`) until no eligible rows remain, so rows after the first page are recalculated in the same run instead of waiting forever behind unchanged earlier rows.
- `LateFeeBeginDateApplyService` centralizes `lateFeeBeginDate` persistence and is reused by normal billing, manual charge creation, counter add-reading formalization, and special billing formalization before `chargeMapper.insert`.
- Focused tests now cover the shared begin-date apply service, keyset pagination across batches, and direct insert path wiring for counter add-reading and special billing.
- Price-diff write-back now applies missing `lateFeeBeginDate` before inserting the replacement unpaid charge.
- Daily recalculation now keeps the outer pagination loop non-transactional and executes each page through `LateFeeRecalculationBatchService.recalculateBatch(...)` with its own transaction boundary.
