Fix integration test fixture ordering to avoid bids2table discovery issue

ds000114_func_derivatives now depends on ds000114_anat_derivatives
directly instead of longitudinal_template_output.  This ensures
rbc functional runs before the template step writes ses-longitudinal
files into the derivatives dir, avoiding a potential bids2table
discovery issue where the ses-longitudinal anat files interfere with
the functional pipeline's anat resolution.

longitudinal_func_output depends on both ds000114_func_derivatives
and longitudinal_template_output to ensure both cross-sectional
functional outputs and the longitudinal template are present before
rbc longitudinal functional runs.
