Register ASP.NET Core health checks and map GET /health. The endpoint
returns 200 with a "Healthy" body by default, making the red test pass.
Smallest change to go green.

Add the BFF Api/Tests skeleton (.NET 10, ASP.NET Core minimal API, xUnit
+ WebApplicationFactory) and a failing test asserting GET /health returns
200 with a Healthy body. The endpoint does not exist yet — the test fails
with NotFound, establishing red before the implementation.
