tiennm99 e165e3c5b6 refactor: flatten data layout to data/, drop update/ overrides ...

- Move 63 Excel files from data/raw/ to data/ (single flat dir)
- Remove all 53 files in data/raw/update/: verified identical SBD
  coverage to raw/ (847349 rows either way), so they added no new
  students — only potential score corrections that can be reintroduced
  later if source is recovered
- Update build-database.js to read data/ directly
- Add scripts/audit-row-counts.js: compares source row count to DB row
  count to verify zero-loss parsing
- Point check-duplicates.js at new data/ location
