Wire Wikidata web routes and add feature tests

[ayoungco]

Motivation

• Wire the existing Wikidata controllers into the app routing so concept pages are reachable under a clear namespace and do not collide with local UUID routes.
• Provide quick, documented proof-of-concept routes for entity pages and typed lists per the Wikidata backend plan.
• Add route-level coverage to prevent regressions and to validate controller behavior without hitting live Wikidata in tests.

Description

• Added a /wd route group in routes/web.php and imported WikidataThingController and WikidataTypeController, exposing GET /wd/item/{qid} and GET /wd/type/{type} with input validation and named routes.
• Introduced tests/Feature/WikidataRoutesTest.php which binds a mocked App\Services\Wikidata instance and asserts entity rendering, type listing, and unsupported-type 404 handling.
• Tests use Mockery to stub entityBasics and sparql responses so controller + view behavior is validated without network calls.

Testing

• Ran php -l routes/web.php which reported no syntax errors.
• Ran php -l tests/Feature/WikidataRoutesTest.php which reported no syntax errors.
• Attempted php artisan test tests/Feature/WikidataRoutesTest.php but it was blocked in this environment due to a missing vendor/autoload.php so the feature test suite could not be executed here.

Not necessary but want to eventually move to some unified/open data model. Give back to the community and all that.
