fix(compare): expert sign-off must-fixes — phase-matched admissions, Ofsted sentinel codes, selective-school copy

M1: admissions rounds are now selected by the active phase tab
(admissionsForPhase) — an all-through school's Year 7 round no longer
masquerades as Reception odds beside pure primaries; honest per-cell and
section fallbacks name the round (Reception / Year 7).
M2: Ofsted sentinel codes (9 = not applicable) never render as judgement
chips, and the sixth-form judgement — previously dropped — now renders
for schools that have one.
M3: 'What this means' is phase- and type-aware: selective schools get
entrance-test framing, secondary faith schools a faith-criteria note, and
the primaries' distance template never appears on the secondary tab
(admissions_policy now exposed in compare school_info).
