* fix: render whiteboard math via KaTeX instead of raw LaTeX text

* fix: recognize single-command LaTeX with a braced argument

The fallback missed valid single-command expressions (\vec{v}, \hat{x},
\overline{x}) whose command is not in COMMON_LATEX_COMMAND, because
commands.length < 2 returned null and they rendered as raw text. Now a
single command counts as math when it carries a braced argument, while
path-like prose (C:\temp) still has no braced argument and stays text.
Add regression tests for both cases.

* fix: exclude Windows drive paths before the common-LaTeX-command check

COMMON_LATEX_COMMAND.test() ran before any path-like check, so C:\alpha,
C:\theta and C:\pi were classified as LaTeX and rendered through KaTeX.

Return early for text starting with a drive letter, and add C:\alpha to the
Windows-path regression cases so a path whose segment matches
COMMON_LATEX_COMMAND is covered.
