feat(detail): surface GIAS identity/contact details, drop unwired sections

Add seven school-identity fields to the detail header (both primary and
secondary views): age range, religious character, nursery and sixth-form
indicators as chips; telephone (tel: link), county and parliamentary
constituency as header details. religious_denomination, age_range and
has_sixth_form were already served; telephone, nursery_provision, county
and parliamentary_constituency are newly wired through the marts query
(with a NULL fallback for un-rebuilt marts, mirroring has_sixth_form) and
the school_info API response.

Remove three UI sections the backend never populated (always null): Year 1
Phonics, the SEN "types of additional needs" breakdown, and the average
class-size card — along with their now-dead props, route plumbing, and the
SenDetail/Phonics types + class_size_avg field.

Extend the e2e detail journey to assert the Phonics section is gone and the
new header fields render when the record carries them.
