Point the tab-order gate at a page that exists

Browse source 
check:spa-tab-order was FAILING with "no .vtl-tab rows found in the composed
tree", which reads as a missing tab rail. The rail is fine. The gate navigated
to a DIRECTORY url — .../doxa-maps-spa/doxa-maps-spa/ — and `bun run serve` is
serve-strict.mjs, which 404s a directory request with no index fallback because
the live static layer does. Measured: the directory url returns 404, the
explicit index.html returns 200.

Under the old `python3 -m http.server` this line passed, since that server
silently resolved a directory to index.html. So the gate was green locally and
would have 404'd against production — the exact defect class serve-strict was
introduced to expose, after it hid a bad url in verify-shell-scroll for a whole
flight. A repo-wide sweep found this was the last remaining directory url in
internal/.

The symptom deserves recording because it was maximally misleading: a 404 page
has no rail, so a missing PAGE and a missing FEATURE produce the same message,
and the line immediately below warns about that same confusion arising from
shadow roots. A correct warning about one cause makes the wrong diagnosis of
another cause more tempting, not less.

Now passes, and what it prints is the canonical Gate-1 chain: 12 rows opening
Big Picture ("dashboard + people-groups grid, stacked"), UPG-100 List, Prayer
Progress, Gospel Resources. Big Picture is tab-1 of the cap-5 SPA, as specified.
