refactor: Improvements to Router TypeScript definitions

[koistya]

• Merge core/router.types.ts into core/router.ts
• Update Route<Component, Query> TypeScript definition (from <Route<Component, Data>)
• Scroll to top when navigating to a new route
• Add query (URLSearchParams) field to the resolveRoute(ctx) context
• Add an error ForbiddenError to be thrown when accessing a protected route

// BEFORE
import { type Route } from "../core";
import Profile from "./Profile";
import { type ProfileQuery$data } from "../queries/ProfileQuery.graphql"; 

// Route for https://example.com/username
export default {
  route: "/:username",
  query: graphql`...`,
  response(data) { ... }
} as Route<typeof Profile, ProfileQuery$data>;

// AFTER
import { type Route } from "../core";
import { type Profile } from "./Profile";
import { type ProfileQuery } from "../queries/ProfileQuery.graphql"; 

// Route for https://example.com/username
export default {
  route: "/:username",
  query: graphql`...`,
  response(data) { ... }
} as Route<Profile, ProfileQuery>;
