Subject: [PATCH] feat(infra): add docker-compose for local MariaDB with Prisma
 schema init

Applies prisma/migrations/*/migration.sql on first container boot via a
sourced docker-entrypoint-initdb.d script, so a fresh container matches a
`prisma migrate deploy` run without needing shadow-database privileges.
