[feature]: Move to app-specific domain

[autonome]

Is your feature request related to a problem? Please describe.

The front-end is currently hosted via HTTP and IPNS/DNSlink at a Fission.com domain.

Once #189 is fixed, it should move to a new domain that's specific to the app, not a specific company.

Describe the solution you'd like

• decide on a domain name
• register it, managed by Filecoin Foundation
• point domain to URL from [feature]: Move to entirely static front-end, hosted on GH or Fleek #189

Describe alternatives you've considered

We tried domains of the companies who were leading development at the time, but that changes.
