Fix build issues and end-to-end tests using adapter api for aws

[conico974]

For aws :

• Fix app-router test
• Fix app-page-router
• Fix page-router

This PR already includes a bunch of changes, and I think it would make sense to first merge this one and fix and probably refactor cloudflare ones in another PR

Pull request overview

This PR updates the AWS build/test setup to use the Next.js adapter API outputs (instead of the legacy NextServer-based runtime path) and bumps dependencies to address build and routing/test failures, with additional local E2E workflow wiring.

Changes:

• Bump AWS Next.js catalog version to 16.1.4 and refresh lockfile (incl. Playwright/Express-related updates).
• Introduce ResolvedRoute.isFallback and filter out prerendered fallback: false dynamic routes during routing to correctly produce 404s.
• Shift the request/runtime path toward the adapter handler flow and update build/copy/plugin logic to support adapter outputs and monorepo packagePath.

packages/open-next/src/core/routing/adapterHandler.ts:39

• In the route loop, returning when getHandler(route) is undefined aborts routing entirely and bypasses the final 404 handling. This can lead to requests never being handled if the first resolvedRoute isn't inlined. Replace the early return with a continue (and only return after a handler successfully runs or after the loop finishes).

	for (const route of routingResult.resolvedRoutes) {
		const module = getHandler(route);
		if (!module || resolved) {
			return;
		}
