Add a reusable websocket helper that sends a JSON command and loops
reads until finding a response containing the expected key. This
handles the printer's unsolicited status messages that arrive on
connect before the actual response. Returns empty string on timeout
instead of throwing.

Parse the model field from the /info JSON response to enable
model-specific features. Add supports_multi_color_print() which
returns true for K2-platform printers (K2 Plus, K2 Pro, K2).

Change start_print() from void to bool with a wxString& msg
out-parameter, matching the error handling pattern used by Duet,
MKS, ESP3D and Flashforge. On failure, the error message is now
reported to the user via error_fn instead of being silently
swallowed. Use BOOST_LOG_TRIVIAL for logging instead of std::cerr.

Move duplicate get_host_from_url() implementations from ElegooLink and
OctoPrint into Http as a static method using the curl_url API. This
eliminates code duplication and provides a single reliable URL host
extraction utility for all print host implementations.
