Removed unsafe-inline JS from CSP and other fixes

- Removed `unsafe-inline` for javascript from CSP.
  The admin interface now uses files instead of inline javascript.
- Modified javascript to work not being inline.
- Run eslint over javascript and fixed some items.
- Added a `to_json` Handlebars helper.
  Used at the diagnostics page.
- Changed `AdminTemplateData` struct to be smaller.
  The `config` was always added, but only used at one page.
  Same goes for `can_backup` and `version`.
- Also inlined CSS.
  We can't remove the `unsafe-inline` from css, because that seems to
  break the web-vault currently. That might need some further checks.
  But for now the 404 page and all the admin pages are clear of inline scripts and styles.
