address code review: fix inclusive to-date filter, add retention error handling

- LoggingService.findLogs(): the `to` date filter compared a date-only
  string (e.g. from a date picker) against a timestamp column, which
  parses to midnight and silently excludes the entire last day. Widen
  it to end-of-day so the range is genuinely inclusive.
- LogRetentionScheduler.cleanupOldLogs(): wrap the delete in try/catch
  and log failures via logger.error, matching the existing convention
  in CashboxExportScheduler/RecurringTransactionsScheduler. Without
  this, a failed nightly cleanup would fail silently - exactly what
  this feature exists to prevent.
