chore: the gap list is current again, and the check is clean

The Navigator was still listed as missing; only split view is. Formula
recalculation stops the walk at the blocks a table cannot be in, or it
visits every run of the document per keystroke. One dead CSS rule goes,
so svelte-check reports nothing at all.

 **Content an imported document loses**
 - Charts are **drawn** from the file (`import/chart.ts`: DrawingML `chartN.xml` and ODF `chart:chart`), but as a picture, not a chart object — a re-export carries the drawing and the numbers behind it are no longer editable. The same holds for an **EMF** metafile (`import/emf.ts`): it is drawn, but as the SVG picture it was rebuilt into, and only from the record set a plot consists of — a hatched brush, a clipping region or a rotated bitmap is skipped. **WMF/SVM** metafiles and OLE objects still keep their box and a placeholder label, and export writes that back out: WMF is a different (16-bit) record format, SVM is StarOffice-proprietary, and an OLE object cannot be rendered without its application
