Store extruder and bed temperatures as min/max ranges instead of single values for more accurate filament specifications. Backend changes: - Add 4 new columns: settings_extruder_temp_min/max, settings_bed_temp_min/max - Keep old columns for backward compatibility (marked deprecated) - Alembic migration copies existing values to both min and max - Update Pydantic models and API endpoints Frontend changes: - Filament model updated with new fields - Create form uses min/max input pairs with Space.Compact - Import from external DB populates both min and max with same value - Label template updated to show ranges: "ET: 190-220 °C" - Template help includes new tags Labels now display temperature ranges like "190-220°C" which is more useful for printing than a single recommended value.
