Rewrite and restyle reaction selector and enable no-sizzle eslint rule (#30453)

Enable `no-sizzle` lint rule, there was only one use in `initCompReactionSelector` and:

- Remove all jQuery except the necessary fomantic dropdown init
- Remove the recursion, instead bind event listeners to common parent container nodes
