site: make the hero panel's finding count reproducible

The marked-up example advertised '3 findings', but the file as written also
draws modern.missing_schema_prefix on the unqualified `Orders` — so anyone who
actually ran it got 4. Schema-qualifying the FROM makes the label exact and
models the practice the rule recommends. Verified: 3 findings, 2 errors, exit 1
under --fail-on error, matching the panel's footer.
