feat(styles): seed current table/multileader style from the file

Bump acadrust to pick up the new $CTABLESTYLE / $CMLEADERSTYLE header
variables, then on load seed the ribbon's active table style and the
tab's active multileader style from the document header so the ✓ marks
the style the file actually declares (DXF). Set Current writes the header
field as the round-trip source of truth, and the style-manager staging
snapshot now covers it. sync_ribbon_styles honours the active table style
instead of always falling back to the first one.

DWG still leaves these at "Standard" until acadrust parses them from the
binary header.
