Confirm before clearing recent projects

[BenJule]

Summary

• add a confirmation dialog before clearing all recent projects
• make No the default choice to prevent accidental deletion
• leave removal of individual recent projects unchanged

Testing

• ran git diff --check
• verified the Clear All confirmation control flow
• verified that the dialog only appears for the empty-filename Clear All action
• no local full build; the change is limited to the existing recent-project handler

Fixes #8351

Hi @BenJule can we use a native dialog for this?

[BenJule]

Thanks @tonghao-bbl. Yes, I've updated the confirmation to use the native wxMessageDialog instead of Bambu Studio's custom MessageDialog wrapper.

No remains the default choice, so the existing protection against accidentally clearing the recent-project list is unchanged.

I also ran a targeted compile check of MainFrame.cpp using the existing Release build flags, and git diff --check passes.

Could you please take another look? Thanks!

Thanks for you quick action. Actually I mean we can use a native looking widget, anyway can you take a screen short of this message dialog so we can make this review faster?

Thanks @tonghao-bbl. I retested the final version with Jenkins build #31 (commit ab863b406d81).

The previous web confirmation has been removed, so Clear all now opens only the native-looking wxMessageDialog.

I verified both paths:

• No is the default choice and leaves the recent-project list unchanged.
• Yes clears the recent-project list as expected.

@zzsoccer214 Please take a look on Mac if the dialog looks good when available
