Adding SSH keys authentication method

[smileoniks-ctrl]

As an option, after creating a node, switch the nodes to use SSH keys (ed25519) generated by the panel. What do you think about adding this functionality?

Nice idea! The panel already supports SSH keys (you can paste a private key manually), but auto-provisioning would be a great UX improvement. We'll add a "Generate & install SSH key" button that creates keypair and installs it on the server automatically. On the roadmap 👍
