docs(pallet-tests): keep multi-line <c> on one line for docfx

The class-level XML doc comment on PalletMeasurementContractTests
wrapped a single `<c>PhysicalAsset &gt; Pallet &gt; Measurements</c>`
span across two source lines:

    /// Per the MTConnect SysML model, the <c>PhysicalAsset &gt; Pallet
    /// &gt; Measurements</c> package declares ...

docfx flattens the wrapped XML doc into adjacent markdown lines,
producing a line that starts with `> Measurements</code> package
declares ...`. The leading `> ` is then re-parsed as a markdown
blockquote, eating the `</code>` close tag and tripping Vue's
"Element is missing end tag" error during the Docs-site CI's Build
VitePress site job.

Reflow the comment so the `<c>...</c>` span fits on one line. The
generated markdown then carries the full code span on a single line
and the blockquote-collision goes away.
