DEV: minor choose topic refactoring (#15233)

* DEV: minor choose topic refactoring

- prevents category to be clickable to make clicking topics easier
- drops jQuery
- uses @action
- uses ? operator where possible
- drops un-needed next/schedule usage

* uses topic-status component and prevents pinned icon to be focusable

* Update app/assets/javascripts/discourse/app/templates/components/choose-topic.hbs
