harktech: set host_type + printer_agent=crealityprint on K2/K2 Pro/K2 Plus presets

The CFS-aware filament sync resolves its agent via switch_printer_agent(),
which reads the preset's `printer_agent` field and falls back to "orca" when
unset -- so the K-series presets need printer_agent="crealityprint" (the id
registered by CrealityPrintAgent) in addition to host_type="crealityprint"
(classic PrintHost/LAN-discovery). Without printer_agent the Device-tab sync
defaults to the Orca agent and CFS sync doesn't engage. Set both on the
F008/F012/F021 models that supports_multi_color_print() covers (not K2 SE).
Both keys are in s_PhysicalPrinter_opts, so a new Physical Printer inherits
them from the preset.
