fix: axios client respects the defaultTimeout (#463)

🤦 the `axios` clients `defaultTimeout` parameter was
essentially unused, possibly since the beginning.

- Add `e2e` tests for `defaultTimeout`, and route level `timeout` for
both `fetch` and `axios`
- Apply `defaultTimeout` on `axios` clients _(fetch was already
correct)_

thanks @henryhobhouse for spotting
