Full restore creates missing tables and suspends foreign keys; --install-apps; clearer messages
Backups now record each table's structure in the dump manifest. The full restore creates tables that do not exist on the new instance (left behind by apps that were removed or are switched off), lists all problems at once, and no longer stops on apps that are missing. Foreign keys are not checked while rows are loaded in name order, and checked again before the restore commits (PostgreSQL: dropped and added back in the transaction). --install-apps installs or enables the apps that were enabled at backup time; --skip-missing-tables leaves out tables of older backups whose structure is unknown. nextcloud-aio is never required. backup:target:add without a key points to backup:key:import, and says that connecting can take a while. Removing a location drops its cached index; a migration removes the cache of locations that are gone. The full-restore test now also runs on PostgreSQL with Mail (foreign keys) and a disabled app.
