feat(cra): route secure-dev breadth to code_security (atom-grain)

Both network_security and code_security are now atom-grain. Per-sub_topic
use_case routing: secure_development -> code_security (best for secure-dev
findings), everything else -> network_security. Findings carry breadth_use_case
so the source context (which atom corpus) is visible under the best-practice depth.
