Library updates and lint fixes (#8099)

* Minor updates only
* Added explicit radix parameter (10) to all Number.parseInt() calls throughout the codebase (new lint rule)
* Updated several @ts-ignore comments to @ts-expect-error for better TypeScript practices (new lint rule)
* Removed unnecessary @ts-ignore comments in some mode files (ditto)
* Used "none return" based arrow functions for some map stuff
* Replaced a `map()` call that didn't return anything to a for() loop
* Fixed up some cypress stuff, noting work for the future
