viewer: subscripted space group and a pathology checklist in the merge window

The space-group hero card (and the "indistinguishable" line) render the short
Hermann-Mauguin symbol as rich text: screw axes subscripted, rotoinversions
overlined (P2_1/c, P4_12_12, Fd-3m). It is built from gemmi's spaced symbol
with short_name()'s monoclinic shortening applied; checked against all 564
gemmi settings to reduce to short_name() once the markup is stripped.

The report's SUMMARY now also records its pathology rows as typed checks
(ReportDocument::checks): PRESENT exactly when one of the row's codes is in
PATHOLOGY_FLAGS, ABSENT when it was measured and did not fire, UNDETERMINED
when it could not be measured. A flag no row stands for gets a check named
after its code, so the list never shows less than PATHOLOGY_FLAGS. The text
report is unchanged. The viewer builds the document once, renders the text
from it and shows the checks phenix.xtriage-style: a green/red/grey light per
pathology, the summary words and fired warnings in the tooltip.
