Fix flaky return-to-path e2e tests (#18580)

## Summary

Fixes flaky `return-to-path` e2e tests that were failing intermittently
in CI merge queue runs.

**Root cause:** In the multi-workspace environment used by CI
(`IS_MULTIWORKSPACE_ENABLED=true`), navigating to
`localhost:3001/settings/accounts` triggers a full page redirect to
`app.localhost:3001/welcome` via `useRedirectToDefaultDomain`. This
redirect is a hard navigation (not a React Router transition), which
clears all in-memory Jotai state — including the `returnToPathState`
atom that stores the path the user should be redirected to after login.
After the redirect, the app has no memory of the intended destination
and falls back to `/objects/companies`.

**Fix:** Before performing the cross-domain redirect in
`useRedirectToDefaultDomain`, read the `returnToPath` from the Jotai
store and pass it as a URL search parameter. On the new page load,
`useInitializeQueryParamState` picks it up from the URL and re-hydrates
the Jotai atom, preserving the return-to-path across the full page
reload.

## Test plan

- [x] Verified locally against production build (`serve -s build`) with
`IS_MULTIWORKSPACE_ENABLED=true` — 33/33 consecutive passes of
`return-to-path.spec.ts`
- [x] Lint passes (`npx nx lint:diff-with-main twenty-front`)
