Fix CI errored tasks for front (#6806)

In this PR:
- revert de-optimization of icons bundle for storybook. This was forcing
the browser to load ~3k files while running stories
- adding lazy loading on Settings route to improve developer experience
(some files will be loaded later)
- fix FE tests: unit, modules stories, pages stories
