Jdv usecase blaas to firewall

[rr404]

Better adapt in new usecase section of trouble shootting or in guides

Inital idea was to add a usecase in there to judge the level of abstraction we should have in them:

Turns out that for this BL usecase I was not happy with the state of the blocklist section and start a few changes

• move integratinos in their own folder
• add first pass of improvements to some pages
  • bl intro https://meet.google.com/ukk-fnwe-hyf?authuser=0
  • bl quick guide https://pr-688.d1to60jd2gb6y6.amplifyapp.com/u/blocklists/getting_started
