Fill the boundary halo cells with the prescribed Dirichlet states.
Only edge ranks have boundary halos that BC code-paths leave alone — those ranks need a pre-filled halo so apply_bcs's early-return (for dirichlet / inflow / supersonic_inlet) reads valid data. Inner ranks: this is a harmless overwrite that halo_exchange will replace on the first residual evaluation.
