Add 'info' command for per-table backup size breakdown

[minguyen9988]

fix #1388

Summary

Add a new info CLI command that shows per-table size breakdown for local and remote backups.

Usage

clickhouse-backup info [-t, --tables=<db>.<table>] [-f, --format=<text|json|yaml|csv|tsv>] [all|local|remote] <backup_name>

Features

• Shows per-table size, part count, and disk breakdown for any backup
• Supports both local and remote backups (or both with all)
• Multiple output formats: text (tabwriter), JSON, YAML, CSV, TSV
• Table pattern filtering with glob wildcards (same syntax as other commands)
• Totals row showing aggregate size and part count

Files changed

• cmd/clickhouse-backup/main.go — Register the info command in the CLI (inserted before the download command)
• pkg/backup/info.go — New file (401 lines) implementing Info(), infoLocal(), infoRemote(), filterTablesByPattern(), and printInfo()

Example output

Backup: my_backup (local)

TABLE              SIZE       PARTS   DISKS
-----              ----       -----   -----
mydb.events        1.2 GiB    42      default
mydb.logs          256 MiB    12      default
-----              ----       -----   -----
TOTAL (2 tables)   1.5 GiB    54
