Fix parse_type_hint for numpy 2.5

Closes #769 (closed)

numpy 2.5 changed numpy.typing.NDArray from a plain TypeVar-parametrized alias into a PEP 695 TypeAliasType. The introspected structure changed:

	numpy ≤ 2.4	numpy ≥ 2.5
NDArray[np.bool]	numpy.ndarray[Any, numpy.dtype[numpy.bool]]	NDArray[numpy.bool] (types.GenericAlias over a TypeAliasType)
typing.get_origin(...)	numpy.ndarray	numpy.typing.NDArray
typing.get_args(...)	(Any, numpy.dtype[np.bool])	(numpy.bool,)

PyTango's parser at tango/utils.py:619-620 relies on the old shape:

if typing.get_origin(dtype) == np.ndarray:
    dtype = typing.get_args(typing.get_args(dtype)[1])[0]

On 2.5 get_origin is no longer np.ndarray, so the branch is skipped entirely; the raw NDArray[...] alias falls through to TO_TANGO_TYPE[dtype] (line 511) → KeyError → the "Cannot translate" error

Fix:

Replace the single-origin check with a dual-path extractor. The scalar type is extracted differently per numpy layout, then the existing SPECTRUM/(dtype,) handling is unchanged.
