Background

The BackupService in web/service/backup.go only works when the panel is running. CLI users need standalone backup and restore subcommands that use the same SQLite/MariaDB CLI tools without starting the web server.

Changes

Added backupCmd and restoreCmd flag sets in main()
Added "backup" and "restore" entries to flag.Usage
Added case "backup": and case "restore": to the switch statement
Added helper functions: runBackup(), runRestore(), dumpMariaDBCLI(), dumpSQLiteCLI(), createTarGzCLI()
Added imports: archive/tar, compress/gzip, encoding/json, io, os/exec, path/filepath, strings, time

Impact

main.go only; no API, database schema, or config changes
Uses existing config package exported functions

Verification

go build -ldflags "-w -s" -o /usr/local/x-ui/x-ui ./main.go passed
gofmt -l -w . && go vet ./... passed
Runtime verification not done (requires sqlite3/mysqldump/mysql CLI tools on a live server)

Risks And Follow-Up

Runtime depends on sqlite3, mysqldump, and mysql CLI tools being installed on the server
Restore is restricted to master nodes only
No automatic MariaDB table drop before restore; manual table cleanup may be needed
