Андрей Бобырев b140cdac43 fix(tunnel): SSH key auth instead of sshpass; init.d boot persistence; copy fallback ...

aarch64-k3.10 Entware does not have sshpass or cronie packages. Switch to ed25519
SSH key auth and persist via /opt/etc/init.d/S99kdns_tunnel instead of cron.

- /api/routers/{rid}/tunnel-cmd: drop VPS_SSH_PASS dependency, generate one-time
  registration token, build install script that:
    1. opkg install autossh + openssh-keygen
    2. ssh-keygen ed25519 if not exists
    3. curl POST pubkey to new register-key endpoint with token
    4. autossh -i <key>  (no sshpass)
    5. /opt/etc/init.d/S99kdns_tunnel for boot autostart
- /api/routers/{rid}/tunnel-register-key: new endpoint, token-auth, appends pubkey
  to ~/.ssh/authorized_keys with kdns-tunnel-{rid} comment for de-dup
- copy button: fallback to document.execCommand('copy') for non-HTTPS contexts
  (navigator.clipboard requires secure context — UI runs on plain http)
