[SM-1762] Bump Jest to 30.3.0

📔 Objective

Update Jest to the new major version 30.3.0

With #19981 the first attempt was made, but it did include a larger change-set than needed and skipped some test cases. This aims to break it up and in case some of the additional changes are needed with another bump of jest-environment-jsdom, we can revisit that PR after this merges into main.,

This PR bumps all required dependencies around Jest and fixes any broken paths or tests due to stricter typescript rules with jest-environment-jsdom (mainly mockImplementation)

Relates to:
#17623
#20202
#19843
