fix(rankings,admissions): correct accuracy issues from education audit

Follow-up audit of the rankings and admissions pages.

Admissions (AdmissionsView.tsx):
- National Offer Day no longer claims offers publish "from 12:01 am";
  release times are set per-council (often late afternoon, some
  overnight), so it now tells parents to check their council's page.
- Secondary preference count no longer states a flat "up to six"
  (that's London/Pan-London); most LAs allow three to six. Mirrors the
  hedge the primary step already used.
- Added the two deadlines that most often catch parents out: selective
  schools' separate entrance-test registration (months earlier), and
  faith schools' supplementary information form sent direct to the
  school. Covered in both the primary and secondary criteria steps.
- Reworded the equal-preference tip so it's precise: order is the
  tie-break among schools you qualify for (you get the highest-ranked
  one), not irrelevant.

Rankings (RankingsView.tsx):
- Subtitle "Top-performing schools by X" -> "Schools ranked by X", so
  it isn't nonsensical for context/equity/absence metrics.
- KS2 progress isn't published for 2023/24 or 2024/25 (no KS1
  baseline). Selecting a primary progress metric on a recent year used
  to dead-end on a generic "No rankings found". Added a scoped caveat
  to the progress hint and an explanatory empty-state (primary only —
  secondary Progress 8 is published).

Added an admissions smoke journey (static content, stable milestones).
Verified with tsc --noEmit and next build.
