   ### What problem does this PR solve?
   
   Issue Number: close #xxx
   
   Related PR: #xxx
   
   Problem Summary:
   The Cloud Recycler checker did not validate V2 delete bitmap metadata 
against active rowsets and object storage, allowing missing, orphaned, or 
inconsistent delete bitmap data to go undetected.
   
   This change adds independent checks for FDB, standalone-file, and 
packed-file storage. It also validates packed-file slice locations, resource 
ownership, reverse references, and reference counts, with focused CheckerTest 
coverage.
