fix: Call vault migration on onboarding's end

In a previous commit we changed the bitwarden client's type from
`webapp` to `web`

This had a side effect on onboarding that would not trigger migration
from konnectors accounts to ciphers as this is prevented on `web`
clients (because cozy-keys-lib is also flagged as a `web` client)

This is a requirement for setting `extension_installed` flag to `true`

The result was the onboarding screen to be always displayed when
accessing cozy-pass-web

To fix this, the cozy-stack now has a new entry point `/settings/vault`
that allows to enforce the migration from cozy-pass-web even if its
client is a `web` one

We want to call this endpoint at the end of onboarding
