Reorder blocks in vue SFCs (#26874)

Reorder blocks in vue SFCs (#26874)

The [recommended order](https://vuejs.org/guide/scaling-up/sfc.html) for
SFC blocks is script -> template -> style, which we were violating
because template and script were swapped. I do find script first also
easier to read because the imports are on top, letting me immideatly see
a component's dependencies.

This is a pure cut-paste refactor with some removal of some empty lines.
