test(targets): pin coach CTA disappears when global flag is off

Mock useFeatureFlags so the suite can drive both the flag-on (CTA
mounts) and flag-off (CTA hides) branches alongside the existing
aiEnabled gate test. Both branches share the all-on default unless
the case overrides it with mockReturnValueOnce, so the rest of the
suite continues to render with the default-mock flag set.
