v0.0.23: ETH display everywhere, local build, web UX fixes

Version: 0.0.22 → 0.0.23, SW cache wz-v3 → wz-v4

TUI:
- Own messages show ETH address (0x...) instead of fingerprint
- Received messages: async ETH cache lookup (resolve on first sight)
- /info shows Identity + Fingerprint
- Welcome message shows ETH address

Web:
- Header shows only ETH address (single element, click to copy)
- Own messages show ETH format
- Received messages resolve sender ETH via /v1/resolve/
- /peer 0x... resolves via /v1/resolve/ endpoint
- Click messages area → focuses text input

Client:
- register_bundle sends eth_address to server
- ETH↔fingerprint mapping stored on registration

Build:
- --local: build on current machine (auto-detect apt/dnf/pacman/brew)
- --local-ship: build locally + deploy to all servers
- --local-clean: build + clean cargo cache
