Convert the OMML matrix element (m:m) to MathML <mtable>. Each m:mr row becomes an <mtr> and each m:e cell becomes an <mtd> wrapping an <mrow> that holds the converted cell content, matching the pattern used by fraction/equation-array/radical/nary converters. - Empty m:e cells are preserved as positional gaps per §22.1.2.32 and render a U+25A1 placeholder by default so the layout matches Word's rendering. m:plcHide in m:mPr suppresses the placeholder (§22.1.2.83). - Remaining m:mPr properties (mcs/mcJc/baseJc) are ignored for now; follow-up work will map per-column justification onto <mtable> columnalign. Spec: ECMA-376 §22.1.2.60
