test(api): remove placeholder CORS test superseded by #1436 (#1441)

Follow-up to #1436.

`internal/api/cors_test.go` was a placeholder: both `TestCORSHeaders`
and `TestCORSHeaderValues` construct `api.NewServer(...)`, discard it,
and then assert against a locally-built `http.HandlerFunc` that has no
CORS middleware — so they never exercised the real stack.
`TestCORSHeaderValues` only `t.Log`s; `TestCORSHeaders`'s only real
assertion (preflight status in {200,204}) ran against a bare handler
that always returns 200. The comments admit as much ("this is a bit of a
hack", "verified via integration tests").

That empty coverage is exactly why the missing `PATCH` in the CORS
`AllowedMethods` (fixed in #1436) went unnoticed.

#1436 added `TestCORSPreflightAllowedMethods`, which drives the real
wrapped handler through the new `Server.Handler()` accessor and asserts
every routed method — including PATCH — is allowed. With that in place
the placeholder carries no remaining coverage, so this PR removes it.
