Migrate element basis evaluation functions to use new topology-aware API.
Changes:
- Add _create_topology_instance() helper to construct topology from Lagrange{T,P}
- Update get_basis() to call get_basis_functions(topology, basis, xi)
- Update get_dbasis() to call get_basis_derivatives(topology, basis, xi)
- Add jacobian() function with embedding support (1D element in 2D/3D space)
- Constraint: B <: Lagrange added to method signatures
Migration from OLD API:
- eval_basis!(B, T, xi) → get_basis_functions(topology, basis, xi)
- eval_dbasis!(B, xi) → get_basis_derivatives(topology, basis, xi)
Maintains compatibility: still returns matrices/vectors for old code interface.
