Permitir a exploradores gestionar, filtrar y sincronizar listas de favoritos con persistencia local y en servidor

[JaviFdez7]

An actor who is authenticated as an explorer must be able to:

• Manage their favourite lists, which includes, listing, creating, modifying, and deleting them using local persistence (in the user’s browsing device).
• Filter their favourite lists according to a keyword, so that the system should only dis-play lists that include the keyword in its name.
• Synchronise their favourite lists with an online server, so that these lists can be acces-sible from other devices. Consult requirement 28 to learn more about this.
