fix(vertico): ensure load order of consult & embark

The precise semantics of use-package's :after keyword is janky (see
jwiegley/use-package#829) and, in the case of 992bd8f7e2, causes
subtle breakage. For one, the remappings in the following :init block
were deferred until embark loaded, so they weren't available at startup,
so they reverted to their old (often vastly inferior) predecessors, like
recentf-open-files instead of consult-recent-files.

Amend: 992bd8f7e2
