In https://github.com/elastic/kibana/pull/31234 there were some extra changes that I've reverted, like use of the `tsconfig-paths` package to magically rewrite import statements to defy the standard node module resolution algorithm, the inclusion of several unnecessary options in the `test/tsconfig.json` file, and changes of the line-endings in the config files. This also brings a few enhancements from https://github.com/elastic/kibana/pull/30190 including a modularized version of the expect.js types, and options for explicit mappings for the PageObjects and services used in ftr tests.
