Corrigé Link-In-Bio List

Fixed adding links and sharing a list on its own domain in the Magpie app

In the Magpie app, Add on a Links list now adds a link, and Share published page works for a list on its own domain.

In the Magpie app, a Links list had no way to add a new link: Add block offered a heading, text, a divider or a Magpie page. Add at the top of the list now starts on a link, with a title and an address, and Block type switches to the other kinds. An empty list offers Add link.

Share published page showed "Link could not be shared" for a list whose own domain is live. It now shares that domain, as the website does.
