fix(copy): the app no longer calls itself hackable

To someone deciding whether an editor may go on a work machine, "hackable"
reads as "can be hacked". The site stopped saying it on 2 October; the app
still did, in five places a user reads:

- the Welcome walkthrough: now the site's own line, "The AI code editor
  that keeps you in control"
- the Customize panel's section: Customization
- the customization extension's name, description and settings title

The extension's id (levelcode-hackability) and its settings keys stay, so
nothing that refers to them breaks. Code comments are untouched.
