fix(auth): address second-round review findings

- OAuth-cancel feedback now keys on the live session, not link_uid: ANY
  signed-in cancel (add-another-account via /auth/login, link, or upgrade)
  redirects to /?oauth=cancelled and gets a neutral "Google sign-in was
  cancelled" toast — the add-account path set no marker and was silent, and
  the shared ?link= message wrongly called an upgrade "account linking"
- drop 127.0.0.1 from the dev OAuth host allowlist: only the localhost
  callbacks are registered in the Google console, so a 127.0.0.1 origin now
  falls back to the fixed callback instead of a redirect_uri_mismatch
- Welcome: extract the shared goResend handler (banner CTA + sign-in link) and
  merge the two adjacent signin-only blocks
