fix: node names everywhere, cloud peer names, sync timeout 180s

- Federation: nodeName() with Node-XXXX fallback for all views + map + sync results
- Cloud: peerDisplayName() replaces raw DIDs, hides onion addresses
- Sync timeout increased to 180s for Tor-connected nodes
- Better error message when sync fails
