fix(seed): number counterparties sequentially, no CP-0099 gap (#59)

CP-0099 implied counterparty ids are sparse/hand-picked; renumber the disabled
supplier to CP-0006 so the seed runs CP-0001..CP-0006 densely, matching how JE
ids are assigned in order. Normalize the CP-0099 test fixtures to CP-0003 too;
CP-9999 stays as the deliberately-absent not-found id.
