Subject: [PATCH] fix(extensions): add HTTP route types and getHttpRoutes to
 Extension interface

HttpRoute, HttpRequest, and HttpResponse types were used by extensions
(withdraw, nip05) but not defined in the shared types.ts. Adds them
here so extensions import from the shared module instead of defining
locally. Also adds getHttpRoutes() as an optional method on the
Extension interface for extensions that expose HTTP endpoints.
