Reject unsupported dispersion=True configurations.

mace_off v0.3.15 creates only MACECalculator; it does not compose TorchDFTD3Calculator. The Pyodide path also creates only MACECalculator, so dispersion=True does not add D3 there. Reject dispersion=True for MACE-OFF23 and for all Pyodide calls. Keep D3 composition only on the local mace_mp path.

In `@src/py/mat3ra/notebooks_utils/pyodide/packages/mace.py` around lines 72 - 82,
The get_mace_model_pyodide function must reject any dispersion=True request
instead of passing it to MACECalculator; also reject dispersion=True for the
MACE-OFF23 configuration, while preserving D3 composition exclusively in the
local mace_mp path.
