### What? Migrate remaining direct `next-webdriver` test callers that have a `NextInstance` to `next.browser()`, and expose the shared `Playwright` browser type from `e2e-utils`. ### Why? `NextInstance.browser` should be the supported browser-opening interface for test fixtures, with `next-webdriver` kept as the private implementation detail. ### How? Updated affected development, e2e, and production tests to call `next.browser()` directly, passing `baseUrl` where tests intentionally target a manually spawned or proxied server. Shared helpers now receive browser callbacks from the test context, and browser types import `Playwright` from `e2e-utils` instead of deriving from `next.browser` or importing from private paths. <!-- NEXT_JS_LLM_PR -->
