feat: node:start auto-provisions config and unlock key

When the wizard calls node:start with {hubUrl, username}, the handler
writes a minimal node.toml and a random unlock.key if they don't exist.
The daemon then creates the keystore on first start using the unlock
file — fully non-interactive.

Existing configs are left untouched: if node.toml or unlock.key already
exist, provisioning is skipped and the node starts as before.
