alt_mysql_restore_payload.sh (the DirectAdmin native-restore hook that imports a plugin-origin backup payload into alt-mariadb) had zero behavioral test coverage - only hook-installation plumbing was tested. Add a fake mariadb/mariadb-dump client stub (tracking a simple existing-databases state file) to exercise the real script end-to-end without a live server, covering: checksum mismatch rejection, overwrite=deny enforcement against an existing database, and the happy-path restore. Add a DA_ALT_MYSQL_SETTINGS_FILE override (same pattern as worker.sh's PLUGIN_DIR) so the script's settings file can be pointed at a test fixture instead of the real system one. Also extend da_integration_install_test.sh to check hook-symlink install/uninstall coverage for database_delete_pre.sh, database_user_password_change_pre.sh, database_user_create_post.sh, and database_destroy_user_post.sh, which were previously untested (only database_create_pre.sh was checked).
