Subject: [PATCH 0/2] Fix misaligned output of git repo structure

While localizing Git 2.52.0, I noticed that the output table from git
repo structure becomes misaligned when displaying UTF-8 characters. For
example:

    | 仓库结构   | 值  |
    | -------------- | ---- |
    | * 引用       |      |
    |   * 计数     |   67 |
    |     * 分支   |    6 |
    |     * 标签   |   30 |
    |     * 远程   |   19 |
    |     * 其它   |   12 |
    |                |      |
    | * 可达对象 |      |
    |   * 计数     | 2217 |
    |     * 提交   |  279 |
    |     * 树      |  740 |
    |     * 数据对象 | 1168 |
    |     * 标签   |   30 |

The previous implementation used simple width formatting with printf()
which didn't properly handle multi-byte UTF-8 characters, causing
misaligned table columns when displaying repository structure
information.

This change modifies the stats_table_print_structure function to use
strbuf_utf8_align() instead of basic printf width specifiers. This
ensures proper column alignment regardless of the character encoding of
the content being displayed.

BTW, I used two AI coding tools (Claude Code and Gemini-CLI) to generate
the commits, and added the "Co-developed-by" trailers in the commit
messages by using one of my opensource project:
