feat(materials): Declare LinearElastic as StatelessConstantTangent

Browse Source 
- Add material_behavior(::LinearElastic) = StatelessConstantTangent()
- Enables generic integration to optimize constant tangent case
- Single line trait declaration, zero code duplication
- Integration computes tangent once and reuses for all IPs
