fix: auto-refresh peers list, show warmup status during daemon startup

- Fix peer timer calling refreshEncryptionState() instead of
  refreshPeerInfo(), so the Network tab now auto-updates every 5s
- Reorder RPC error handling so warmup messages (Loading block index,
  Verifying blocks, etc.) display in the status bar instead of being
  masked by the generic "Waiting for dragonxd" message
