User feedback — the wa.me/... and t.me/... subtitles under "Chat
WhatsApp Kami" / "Chat Telegram Kami" leaked the raw URL into the UI.
Just the label now, matching how typical "contact us" menu entries
read. Tap still launches the deeplink from backend config.
Drop the unused `SupportHandle.displayHandle` getter that produced the
scheme-stripped subtitle — no other call site.
