v1.1.2 — works with a remote node out of the box

Setup fix (upgrade recommended; no settings change).

WordPress's wp_safe_remote_* permits only a short list of ports (80, 443, 8080, ...) as an
SSRF guard and silently blocks Monero RPC ports such as 18081 (mainnet) and 38089
(stagenet). So pointing the plugin at a remote node failed until you hand-added an
http_allowed_safe_ports filter — a wall a tester hit on the Monero forum.

The plugin now whitelists only the ports of your own configured node(s) automatically; the
safe-HTTP guard still protects every other host and port. Remote nodes work on a fresh install.

Thanks to the tester who reported it (and donated). 🙏
