fix(list/map): badge report-card schools as Report Card, not their carried-forward grade

The search-result cards and map pins keyed report-card detection off
ofsted_framework === 'ReportCard', but the API sets ofsted_framework to the
raw event grouping ('Schools - S5'); worse, ofsted_grade (the carried-forward
legacy grade) was checked first and won. So report-card schools were badged
by their old grade — Barclay's pin/card read 'Outstanding · 2021' instead of
'Report Card · 2026'. Same root cause as the detail-page fix, different
surface.

Expose ofsted_rc_date on the list serialization (the report-card inspection
date, non-null only for report cards) and make both badge builders treat a
present rc-date as winning over any grade, using its year. Removes the dead
framework === 'ReportCard' branches.
