fix: reconcile stale manualBackupBatchJournalCoverage when contiguous earlier journal coverage is rebuilt

Browse Source 
- Add hasContiguousJournalCoverageThroughFloor to check if current
  batchJournal contiguously covers back through the old retained floor
- Add reconcileManualBackupBatchJournalCoverage that clears stale
  coverage when actual journals have bridged the gap
- Self-clean during normalizeGraphRuntimeState (load-time) and
  appendBatchJournal (write-time)
- findJournalRecoveryPoint now uses reconciled coverage so stale
  manual backup floors no longer block valid reverse-journal recovery
- Add regression tests for gap-not-yet-bridged and bridged scenarios
