feat: Federation UI polish — modals, backgrounds, scroll, names, blocked

- Federation page uses bg-web5.jpg background
- Invite code in full-screen modal with type label (Link/Peer)
- Join modal upgraded to full-screen with backdrop blur
- "Untrusted" renamed to "Blocked" in trust selector
- Your Nodes / Peers containers: max-h-[60vh] with inner scroll
- Server name from Settings shown on DID card + network map
- DID sync between Web5 and Federation on rotation
