test(theme-studio): cover the face-docs dump helper and syntax map

I added ERT tests for face-docs-dump.el: the pure first-line extractor across Normal/Boundary/Error inputs (multi-line, leading blanks, whitespace collapse, empty, whitespace-only, nil/non-string), and the syntax-category resolution (kw to the keyword-face doc, bg and p to default, the faceless dec absent). run-tests.sh loads the new file alongside the build-theme tests in the same batch.
