fix(api-docs): declare bearerAuth security scheme in OpenAPI spec

defineRouteMeta() blocks on admin handlers reference a "bearerAuth" security scheme, but nothing declared it globally — Scalar would render those endpoints as having an unknown auth method. Add the scheme to nitro.openAPI.$global.components.securitySchemes so it's recognised across the whole spec.
