[feature] epic - remove playwright and use pyppeteer-ng directly

[dgtlmoon]

There is no reason to use playwright anymore now that https://github.com/dgtlmoon/pyppeteer-ng exists.

This library works "good enough" for our basic scraping/checking requirements. Now we can talk directly from Python/CDIO into the Chrome browser, no need for a middle "node" process (horrible!!)

It's important to remember that Playwright is written as a TESTING library first, it's not meant exactly for our use-case.

The main two drawbacks with playwright are

• It spins up a very heavy node process for every watch PLUS the browser
• Is a lot more platform dependant
• Less code to maintain
• pyppeteer-ng is async based (so is playwright, tho we use it in sync mode)
• Way lighter docker builds
• Faster checking

Problems - may impact robot-evasion abilities, we will see.

Todo

• use a small stealth plugin Using 2.0.0rc4 pyppeteerstealth for puppeteer fetches #2203
• remove playwright from codebase and docker build(!)
• add nice stuff like [feature] Block loading of resources in Playwright e.g. stylesheets, fonts, media #2229
• and a UI to configure the user-agent overrides (plus warnings about SEC-UA etc)
• show how many kb/mb each 'fetch' used
• enable/disable cache options
