feat(cli): suffix client names with last 7 chars of npub in remote mode

- clients add: appends _<npub_suffix> to name when daemonUrl+nsec are set
- clients list: filters to only clients matching our npub suffix, strips suffix for display
- clients delete: auto-appends suffix to id before sending if not already present
- adds getNpubSuffix() helper in daemon-client.ts
