harktech: normalize Creality K2 filament profiles per repo convention

CI flagged ~150 K2 profile files for using space indentation; repo convention
is tab indentation. Ran the upstream-provided fixer:

    python3 scripts/orca_filament_lib.py -v Creality -p filament -f --force

Mechanical normalization:
- Spaces → tabs (1 tab per indent level)
- Field ordering normalized (name + type first)
- Single-value scalar fields converted to single-element arrays where the
  schema expects arrays (filament_cost, filament_density,
  temperature_vitrification, filament_max_volumetric_speed)

No semantic content changes. Pre-existing issue from the original K2
profile import; touching these files in the multicolor_method strip
brought them into the validator's PR-diff scope.
