Support for oversampled-PSF simulation (PyAutoLabs/PyAutoGalaxy#482): SimulatorImaging.via_image_from gains image_is_convolved: bool = False to skip internal convolution for images already convolved at the fine resolution; Convolver.from_gaussian passes through convolve_over_sample_size. Simulate-and-fit consistency test ties the simulator path to the fit-side convolution exactly (chi²≈0). Suite: 863 passed. Merge first in the #482 chain.

…le kwarg (#482 support)

SimulatorImaging.via_image_from gains image_is_convolved (default False,
behaviour unchanged): skip the internal PSF convolution when handed an
already-convolved image, e.g. one convolved at the fine resolution by an
oversampled Convolver. Convolver.from_gaussian passes through
convolve_over_sample_size. Supports oversampled-PSF simulation
(PyAutoLabs/PyAutoGalaxy#482).
