scopes is a NonEmptyArray, so a hand-written `scopes: []` row does not degrade to a scope-less oauth method — it makes the whole integration config undecodable, and the integration then offers no auth method at all. The editor codec already omits the key for an empty list; these tests pin that constraint so it is visible at the place that must respect it.

Summary
Context
Some MCP servers advertise fixed OAuth scopes but omit a protected-resource identifier from DCR. Executor then tries resource scope discovery and fails with:
Cannot discover OAuth scopes: the client has no resource configuredDeclared scopes now take precedence, so
scopes: ["mcp"]works without a client resource.Related to #1330.
Verification

apps/host-selfhost/src/platform-credential.test.ts; that test passes in isolation.
