test(html): read a few files in a second config

[andiwand]

The reference output renders every file in one config, so a toggle that config does not set is covered nowhere. Nothing renders dark, and the page margins we turn on here hide the reflowed text document the library actually ships by default — the 3mm inset added in #698 appears in no reference file at all.

The mechanism

A test file may now carry a ConfigVariant — a name plus a deviation applied last to the config — and is rendered a second time into a sibling directory suffixed with that name. pdf_text_mode was the one hand-rolled case of this and becomes the first row of the table, keeping its -single path byte for byte.

The suffix keeps every output directory at the same depth, so the link to the shared resources/ is identical in the variant and in the default.

What is covered now

Variant	Config	Files
single	pdf_text_mode = single_layer	one pdf (as before)
dark	color_scheme = dark	one file per view: odt, odp, ods, txt, zip, otf
system	color_scheme = system	txt — the media-query wrapper around the same styles
reflow	text_document_margin = false	odt, docx
read-only	editable = false	odt

Dark mode is pinned per view, not per format — document, spreadsheet, text, filesystem and font each carry their own dark stylesheet. The pdf view honors no color scheme (FileTypeCapabilities::color_scheme says so), and no test file reaches the image view at all, so that one stays uncovered.

Verified

Every pre-existing reference file is byte-identical after the change — the refactor moves nothing. Each new output was inspected in a browser: dark renders dark and readable in all five views, system differs from dark only by media="(prefers-color-scheme: dark)", reflow drops the page box and picks up .odr-text-flow{padding:3mm}, and read-only drops contenteditable and data-odr-path.

Reference output

The shipped resources were a few pull requests behind: document.css missed the 3mm inset and the dark stylesheets, text.js the batched line-number sizing from #696. Regenerated with this, so the pins move for those too.
