What does this PR do?

Refactors the Flux2 pipeline tests to the new mixin structure from #14113: a Flux2PipelineTesterConfig plus TestFlux2Pipeline(PipelineTesterMixin) and TestFlux2PipelineMemory(MemoryTesterMixin), mirroring the flux port.

Existing coverage is kept: test_fused_qkv_projections and test_flux_image_output_shape, with dummy inputs switched to output_type="pt" and the slice indexing adjusted for the channels-first layout. No caching tests are added since the old suite had none.

Shouldn't be using np.allclose().
