test(ids): expand SCAN_CONFIG count to 15 for new core-docs category

The previous test pinned `SCAN_CONFIG.length` at 14 (10 original + 4
NOG-16A). Adding `core-docs` raises the count to 15. Test name and
assertions updated accordingly. Added a type/basePath assertion for
the new `core-docs` entry alongside the existing checks.

Suite: 96/96 pass (was 95/95 — net unchanged in pass count because the
pinning test simply changed its expectation).
