TypeScript is a superset of JavaScript, converting the entire theme to TypeScript allows us to receive much more feedback on possible issues made in package updates or our own typos, furthermore, it allows to transpile properly to lower specs. This PR couldn't be done in smaller commits, a lot of work needed to make everything *work properly*: - A browser baseline has been set that requires minimum **Chromium 93, Firefox 92 and Safari 15** (proper visuals/operation on older browser versions is not guaranteed) - LightningCSS now handles minification and prefix creation for CSS. - All hardcoded polyfills and support for previous browser baseline versions have been removed. - Convert codebase to TypeScript. - Convert IIFE to ESM, handling globals with IIFE is cumbersome, ESM is the standard for virtually any use of JS nowadays. - Vite now builds the theme without the need for `vite-plugin-static-copy`. - `searxng.ready` now accepts an array of conditions for the callback to be executed. - Replace `leaflet` with `ol` as there were some issues with proper Vite bundling. - Merged `head` with `main` script, as head was too small now. - Add `assertElement` to properly check the existence of critical DOM elements. - `searxng.on` renamed to `searxng.listen` with some handling improvements.
