chore: use isolatedModules tsconfig everywhere (#620)

Replaces the deprecated `ts-jest` config of the same name.

Also includes some small alignments of `tsconfig.dev.json` files with
their corresponding parent, where previously missed.
Also removes `dom` from `integ-runner` since this is not needed.
