Expected (written 20:15Z, before the run): Paperless-ngx holds 47 documents (8 failed imports) before.
1. Stop + Remove with "keep my data" (remove_hdd_data=false, remove_backups=false) -> app gone, data folder kept, listed under "Megőrzött adatok".
2. Install again with no choice -> the install refuses 409 kept_data_choice and offers "use" with a named copy and its date. Nothing installed.
3. Install again with "use" -> 202, a load from the newest copy, then the app runs and shows 47 documents.
Risk to watch: a document added after the newest copy would have files on the drive but no row in the database.
