Add placeholder subplot_fit_quick for weak lensing and combined fits

Placeholder quick-update functions that delegate to the full subplot:
- subplot_fit_quick for FitWeak (writes fit_quick.png)
- subplot_fit_combined_quick for multi-dataset imaging fits

Will be replaced with lighter-weight renders in future.
