Fix: check bulk mail delete permissions for the whole batch up front

ProcessedMailViewSet.bulk_delete checked permissions inside the delete
loop, so an unpermitted id returned 403 only after the mails ahead of it
had already been deleted. Resolve the permitted set once via
permitted_object_ids and reject before deleting anything, which also
drops the per-mail permission queries.

-    `zstd` (or `lzma`/`bzip2` where those modules are unavailable) cannot be

 If `--data-only` is provided, only the database will be exported. This option is intended
 to facilitate database upgrades without needing to clean documents and thumbnails from the media directory.
