fix: resolve ES modules compatibility in E2E test files

- Replace __dirname with import.meta.url pattern for ES modules compatibility
- Add fileURLToPath imports to all E2E test files
- Fix duplicate require statements in setup-verification.spec.ts
- Update playwright.config.ts to use relative path instead of __dirname

This fixes the 'ReferenceError: __dirname is not defined in ES module scope' error
when running Playwright tests in the ES modules environment.

+# get-nonce
+
+just returns a **nonce** (number used once). No batteries included in those 46 bytes of this library.
+
+---
+
+- ✅ build in `webpack` support via `__webpack_nonce__`
+
+# API
+
+- `getNonce(): string|undefined` - returns the current `nonce`
+- `setNonce(newValue)` - set's nonce value
+
+## Why?
+
+Why we need a library to access `__webpack_nonce__`? Abstractions!
+
+"I", as a library author, don't want to "predict" the platform "you" going to use.
+"I", as well, want an easier way to test and control `nonce` value.
+
+Like - `nonce` is supported out of the box only by webpack, what you are going to do?
+
+This is why this "man-in-the-middle" was created.
+Yep, think about `left-pad` :)
+
+## Webpack
+
+> https://webpack.js.org/guides/csp/
+
+To activate the feature set a **webpack_nonce** variable needs to be included in your entry script.
+
+```
+__webpack_nonce__ = uuid(); // for example
+```
+
+Without `webpack` `__webpack_nonce__` is actually just a global variable,
+which makes it actually bundler independent,
+however "other bundlers" are able to replicate it only setting it as a global variable
+(as here in tests) which violates a "secure" nature of `nonce`.
+
+`get-nonce` is not global.
+
+## Used in
+
+- `react-style-singleton` <- `react-remove-scroll` <- `react-focus-on`
