The first message of a new chat topic is a long tree, and on phones it fills the whole screen before the actual conversation starts:

├──New chat
├──Department: Support
├──ID: 1234
├──Nick: Visitor
├──Referrer: xn--e1afmkfd.xn--p1ai/pricing#contacts
├──Page title: Pricing

This PR keeps the same information in three lines:

🆕 #1234 · Support
👤 Visitor · 🇩🇪 Germany · 203.0.113.10
📄 Pricing        ← link to the referrer
─────────────
(chat messages as before)

• Chat id in bold, department next to it.
• Nick, Telegram username and phone (when known), country flag + name, IP in <code> (one tap to copy, no phone-number autolink).
• The page is a link titled with the page title; without a title the readable address is shown (IDN host decoded). Full referrer stays the link target.
• Additional data lines use ▫️ key: value; previous chat messages start with 🕘 #<previous chat id>:.
• All values are HTML-escaped (the message is sent with parse_mode HTML; before, a < in a nick or page title could break the message).
• The card is built in TelegramLiveHelperChatOperator::buildChatCard() with small helpers countryFlag() and formatChatPage(), so it is easy to adjust.

No settings or database changes.
