Jukka Aho d3a8239642 test(elements): add CElement real basis functions test ...

New 285-line test file verifying CElement uses real Lagrange basis:
- Tests Tri3 and Tet4 linear interpolation (exact at nodes)
- Tests gradient computation for scalar and vector DOFs
- Validates partition of unity property (sum of basis = 1)
- Tests linear reproduction (linear functions reproduced exactly)
- Tests deformation gradient for VectorDOF{2}
- Verifies basis functions from basis_generated.jl, not stubs

Ensures CElement correctly uses actual Lagrange basis functions
with proper mathematical properties.
