fix(search): tag only what the register records

The secondary row tested the admissions policy with includes('selective'),
which "Non-selective" passes, so every comprehensive (Burntwood, Graveney)
was tagged Selective. It now needs an exact "Selective".

Both rows excluded only "Does not apply" from the religious character, so a
school recorded as "None" got "Faith priority" (Putney High) or a bare
"None" chip (Abacus Belsize Primary). hasReligiousCharacter() treats both of
the register's no-faith values as no faith.
