Modular Smithery

Bump mod version and centralize composed display names: introduce moltenName/moltenBucketName and impressedSandName to derive fluid, bucket and impressed-sand names from material/part lang atoms. Replace ad-hoc i18n checks with PartItem.modifierDescription and reuse it in JEI, tool and armor tooltips. Update bonus-slot calculation to account for bonus_slots_per_level*level. Register impressed-sand blocks/items with composed names; simplify FluidType to use material id for names/textures. Add generic lang format keys and remove many per-material/per-fluid entries. Also update item colors and docs/comments.
