grant0013 598df9ff0b Add Creality K-series LAN discovery via DNS-SD mDNS
When a user adds a Creality K-series printer (host_type=crealityprint)
and clicks the existing "Browse" button in the Physical Printer dialog,
dispatch to a new CrealityDiscoveryDialog that finds K2 / K2 Plus /
K2 Pro printers on the LAN automatically. For other host types the
button keeps its existing BonjourDialog behaviour.

  CrealityHostDiscovery (src/slic3r/Utils/CrealityHostDiscovery.{hpp,cpp})

    Wraps the vendored cxmdns wrapper from the previous commit:

      static std::vector<CrealityHost> scan(bool probe_info = true);

    Calls cxnet::syncDiscoveryService({"Creality", "creality"}) to find
    K-series printers via DNS-SD, dedupes by IP, then optionally HTTP
    GETs http://<ip>/info on each match to fetch the model code
    (F008 = K2 Plus, F012 = K2 Pro, F021 = K2) and MAC. Returns enriched
    {ip, hostname, model_code, model_name, mac, cfs_capable} entries.

  CrealityDiscoveryDialog (src/slic3r/GUI/CrealityDiscoveryDialog.{hpp,cpp})

    Modal dialog with a wxListView showing Model / Hostname / IP per
    discovered host. Runs CrealityHostDiscovery::scan() synchronously
    with wxBusyCursor + wxWindowDisabler (5-10s total wait). User picks
    one, dialog returns the IP via selected_ip().

  PhysicalPrinterDialog (src/slic3r/GUI/PhysicalPrinterDialog.cpp)

    The "Browse" button's click handler now reads host_type from the
    edited config. If htCrealityPrint, opens CrealityDiscoveryDialog
    and writes "http://<ip>" into the print_host field. Otherwise the
    existing BonjourDialog path runs unchanged -- no behaviour change
    for OctoPrint / Moonraker / Klipper users.

No new UI surface: one existing button now does the right thing per
host_type, mirroring how Creality Print discovers its own printers.
