Use flex instead of float for sort button and search input (#25519)

Right now some sort buttons beside search input are unclickable because
#25338 removed `max-width` and the sort button is using float, sort
button is then covered by the `input`.

The way to fix this in this PR is changing the layout to `flex` and put
`input form` and sort `button` into `secondary menu`.
