Problem description

Some analysis features in FEM are supported by multiple solvers while some are supported only by selected solvers. However, there's no information at all about this, making it highly confusing for new users. Here's what we can do about it:

~~1. Add this information on the wiki - that's easiest to do but not sufficient, in my opinion~~
2. Add this information to the tooltips in GUI
3. Show warnings/errors when trying to run analyses with features not supported by the selected solver
4. Disable (gray-out) the analysis features not supported by the currently selected solver - I would choose this approach, eliminating the risk of mistakes like this: https://forum.freecad.org/viewtopic.php?t=81964

研究方向: Examine the FEM module's solver definitions (e.g., in src/Mod/Fem/Gui/ and Python files) and how analysis features are registered. Look at existing tooltip patterns in other workbenches. The issue suggests three approaches: updating tooltips, showing warnings, or disabling features. Start by understanding the data model linking features to solvers, then implement the chosen approach in the GUI layer.
