init: WordFileParse docx→HTML 解析服务（含 Word EQ 域公式修复）
服务：Spring Boot 3.2 + docx4j 8.3.9，POST /api/v3/server_office_file/file/parse
接受 .docx，返回 HTML（公式 → LaTeX，图片 → RustFS 外链）
公式支持三类来源：
- OMML（Word 2007+ 公式） → Python omml_mathml2latex
- MathType OLE 对象 → Ruby mathtype2mathml → MathML → LaTeX
- Word EQ 域（老教辅主力） → EqToLatexUtil（本次新增）
本次改动：
1. 新增 java-svc/.../core/EqToLatexUtil.java：
移植自 jby backend-services office-core，EQ 语法 → LaTeX
（\f→\dfrac、\r→\sqrt、\i→\int/\sum/\prod、\s→^{}/_{}、\b→\left\right、
\a→array、\x→\boxed/\overline、\o\al 堆叠、圈码、化学符号、极限、连等式）
品牌标记 JBYU* → WPU*，与采集端一致
2. CtoMathFinder：接上 EQ 分支（原为 not-ported 桩），域代码经
EqToLatexUtil.convert 转 LaTeX 写入 eqLatexMap（WPEQNUM 占位符）
3. WordParseUtil.dealPlaceholder：EQ 的 LaTeX 同样加 \( \) 包裹
（原先因 WPEQNUM 例外不加包裹，前端/MathJax 不渲染）
修前症状：教辅 Word 里分式/方程组/上下标整段丢失（如 {−1/3, 1} 变成 {－，1}）
修后实测：46 份教辅 2908 处 EQ 域全部还原，公式总数 2954 处、零未包裹残留
安全：application.yml（含 RustFS 密钥）不入库，提供 application.yml.example；
OssService 的 @Value 默认密钥已清空

r"""
|

Visitor for <mlabeledtr> (labeled table row) MathML elements.
|
||||
|
||||
The <mlabeledtr> element is used in tables (<mtable>) to create a row with
|
||||
a label. The first child is the label, and remaining children are table cells.
|
||||
Labels are typically used for equation numbering or row identifiers.
|
||||
|
||||
In LaTeX conversion, the label is typically rendered separately or as part
|
||||
of the row depending on context. For simplicity, we render label followed
|
||||
by cells, separated by &.

Handles <mlabeledtr> (labeled table row) MathML elements.
|
||||
|
||||
Converts labeled table rows to LaTeX array/matrix rows. The first child
|
||||
is treated as the label, remaining children are table cells.
|
||||
|
||||
Examples:
|
||||
Labeled equation row:
|
||||
<mlabeledtr>
|
||||
<mtd><mtext>(1)</mtext></mtd>
|
||||
<mtd><mi>x</mi></mtd>
|
||||
<mtd><mi>y</mi></mtd>
|
||||
</mlabeledtr>
|
||||
→ (1) & x & y
|
||||
|
||||
Simple labeled row:
|
||||
<mlabeledtr>
|
||||
<mtd><mn>1</mn></mtd>
|
||||
<mtd><mi>a</mi></mtd>
|
||||
</mlabeledtr>
|
||||
→ 1 & a
|
||||
|
||||
Three-column with label:
|
||||
<mlabeledtr>
|
||||
<mtd><mtext>Label</mtext></mtd>
|
||||
<mtd><mi>x</mi></mtd>
|
||||
<mtd><mo>=</mo></mtd>
|
||||
<mtd><mn>5</mn></mtd>
|
||||
</mlabeledtr>
|
||||
→ \text{Label} & x & = & 5
|
||||
|
||||
Note:
|
||||
The label (first child) is rendered as a regular cell. LaTeX doesn't
|
||||
have a direct equivalent for MathML labeled rows, so we treat it as
|
||||
a standard row with the label as the first column.
