fix: paginate shared Vercel env var fetch in onboarding + pull

getVercelSharedEnvironmentVariables/...Values read only the first page (~25) of
the shared env endpoint, silently dropping the rest. The shared endpoint
(/v1/env) paginates with a next-cursor the SDK can't follow, so add a raw-fetch
cursor walk (#fetchAllSharedEnvsRaw) that loads every page, via a new
getVercelClientAndToken accessor. Onboarding and pullEnvVarsFromVercel already
decrypt and save the shared values.
