dillard eb9100a74d Fix review findings: catalog writes, user restore consent, retention validation
Catalog: forgetting a user export or purging trash now writes the catalog
before deleting the objects, so a crash leaves at most an unreferenced file
instead of a catalog entry pointing at nothing. Per-user backup and the
safety export reopen the repository inside the catalog lock, so they build
on the latest catalog generation.

Commands: backup:user:backup and backup:user:restore resolve the location
before asking to install user_migration, and a successful install always
stops with a rerun instruction. backup:retention rejects a malformed
--user-last before changing any policy. backup:key:import fails clearly
when the passphrase file cannot be read.

Never imports over a live account. Modes:
replace (default) safety-exports the current account first, then deletes and recreates it
fresh from the backup, under the same user id
as-backup restores into a new account "<uid>-bak" (or "-bak-2", ...) instead, so an admin can
compare and transfer by hand; Nextcloud cannot rename a user id, so the backup gets
the new name, never the existing account
Example:
occ backup:user:restore offsite users/alice/20261005T120000Z-ab12cd34
occ backup:user:restore offsite users/alice/20261005T120000Z-ab12cd34 --mode=as-backup
