Keep mockStatic import in CleanupMockitoImports when type info is incomplete

[timtebeek]

What's changed

CleanupMockitoImports keeps a curated list of Mockito method names (MOCKITO_METHOD_NAMES). When a call's type information isn't well-formed (e.g. an older Mockito on the classpath, or surrounding types that don't fully resolve), the recipe relies on this list to recognize the call and avoid removing the still-needed static import.

mockStatic (and its sibling mockConstruction) were missing from that list — only mock was present. As a result, import static org.mockito.Mockito.mockStatic; was wrongly removed whenever the mockStatic(...) call's type couldn't be resolved, even though it was still in use.

This PR adds mockStatic and mockConstruction to the list, and adds a reproducing test.

Context

Reported via a Moderne result on moderneinc/rewrite-ai-search where mockStatic was being stripped from SpellCheckCommentsInFrenchTest.java despite being used.
