Archive location (Gitea issue 7): ARCHIVE_ROOT, Admin file-locations API, archive-copy job, doctor check

A filed packet's sealed data book, documents and a manifest are copied to the archive folder by the worker.
A failed copy never blocks filing: it is retried with backoff and raises the archive_failed condition.
