refactor: rename allowedHosts to hostnames (#413)

* refactor: rename allowedHosts to hostnames for DNS rebinding config

The old name confused users who thought it was related to CORS.
"hostnames" communicates that you're declaring the daemon's own
hostnames, not granting access to external parties.

Backward compatible: old config files (daemon.allowedHosts), env var
(PASEO_ALLOWED_HOSTS), CLI flag (--allowed-hosts), and Nix option
(allowedHosts) all still work as deprecated aliases.

* fix(nix): update npmDepsHash to match current package-lock.json
