Problem

On the Nodes page, nothing showed where a node's server is. With several nodes, an admin had to remember which server is in which country.

Change

• API (nodes_api.py):
  • each node row gains country (ISO code), from the node's address and the panel's own MaxMind data;
  • a host name is resolved first, IPv4 preferred;
  • no outside service is called;
  • the result is kept in redis for a day, or an hour when unknown.
• Card (NodesView.vue): the flag emoji before the node's name, with the country's name (Intl.DisplayNames) on hover.

Screenshots

The "after" shots come from the test servers, which run this PR together with the Nodes "Show more" (#94) and "Ping" (#95) PRs, so they also show those buttons. This PR adds only the flag.

Before	After

Tested

• On main (a parent with two nodes, panel restart): both nodes got the right country from their address, one by an IPv4 name and one by an IPv6 name.
• Shown on desktop, dark, mobile and Persian RTL.

Review

• Confidence: High (>90%) — one read-only field; the lookup is local and cached.
• Complexity: Simple — one API field and the card's title.
• Note: Windows has no flag emoji, so its browsers show the two letters (e.g. "ES") in place of the flag.
