Override the source-model filament palette (hex #RRGGBB per 0-based slot) used to colour
paint_color facets, instead of reading it from project_settings.config. For consumers that
already hold a corrected/richer palette (e.g. re-rendering a sliced .gcode.3mf). Ignored when
empty; the file's own palette is still read.
