feat(security,ui): self-host React deps, Tailwind, fonts; strict CSP; local QR; better selection state

Replace CDN React/ReactDOM/Babel with local libs; remove Babel and inline scripts
Build Tailwind locally, add safelist; switch to assets/tailwind.css
Self-host Font Awesome and Inter (CSS + woff2); remove external font CDNs
Implement strict CSP (no unsafe-inline/eval; scripts/styles/fonts from self)
Extract inline handlers; move PWA scripts to external files
Add local QR code generation (qrcode lib) and remove api.qrserver.com
Improve SessionTypeSelector visual selection (highlighted background and ring)
Keep PWA working with service worker and offline assets
Refs: CSP hardening, offline-first, no external dependencies

+# p-locate [![Build Status](https://travis-ci.org/sindresorhus/p-locate.svg?branch=master)](https://travis-ci.org/sindresorhus/p-locate)
+
+> Get the first fulfilled promise that satisfies the provided testing function
+
+Think of it like an async version of [`Array#find`](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Array/find).
+
+
+## Install
+
+```
+$ npm install p-locate
+```
+
+
+## Usage
+
+Here we find the first file that exists on disk, in array order.
+
+```js
+const pathExists = require('path-exists');
+const pLocate = require('p-locate');
+
+const files = [
+	'unicorn.png',
+	'rainbow.png', // Only this one actually exists on disk
+	'pony.png'
+];
+
+(async () => {
+	const foundPath = await pLocate(files, file => pathExists(file));
+
+	console.log(foundPath);
+	//=> 'rainbow'
+})();
+```
+
+*The above is just an example. Use [`locate-path`](https://github.com/sindresorhus/locate-path) if you need this.*
+
+
+## API
+
+### pLocate(input, tester, [options])
+
+Returns a `Promise` that is fulfilled when `tester` resolves to `true` or the iterable is done, or rejects if any of the promises reject. The fulfilled value is the current iterable value or `undefined` if `tester` never resolved to `true`.
+
+#### input
+
+Type: `Iterable<Promise | unknown>`
+
+An iterable of promises/values to test.
+
+#### tester(element)
+
+Type: `Function`
+
+This function will receive resolved values from `input` and is expected to return a `Promise<boolean>` or `boolean`.
+
+#### options
+
+Type: `Object`
+
+##### concurrency
+
+Type: `number`<br>
+Default: `Infinity`<br>
+Minimum: `1`
+
+Number of concurrently pending promises returned by `tester`.
+
+##### preserveOrder
+
+Type: `boolean`<br>
+Default: `true`
+
+Preserve `input` order when searching.
+
+Disable this to improve performance if you don't care about the order.
