Subject: [PATCH] feat: Add MATLAB syntax highlighting support for code blocks
 (#20773)

* feat: Add MATLAB syntax highlighting support for code blocks

Add MATLAB syntax highlighting support by fixing issues in both CodeEditor (editable) and CodeBlock (read-only) components.

Changes:
- CodeEditor.svelte: Added 'matlab' alias to CodeMirror's Octave language (MATLAB-compatible syntax)
- CodeBlock.svelte: Fixed highlight.js usage to use highlight() directly when language is recognized, falling back to highlightAuto() only for unknown languages

* revert: not needed
