fix(showcase): fix docker-compose.local.yml aimock config + remove dev-local.sh

- Mount D5/smoke/feature-parity fixtures into aimock via volumes
- Add --host 0.0.0.0 so other containers can reach aimock
- Switch healthcheck from curl to node fetch (aimock image has no curl)
- Delete dev-local.sh (redundant with bin/showcase CLI)
