dev: add Kratos + Mailpit local-dev stack

docker-compose.dev.yml gains a Kratos identity service (public :4433 / admin
:4434) and a Mailpit SMTP catcher for local onboarding email codes, plus a
postgres-init mount. deploy/local/kratos/ holds the local Kratos config +
identity schema (placeholder dev cookie secret only). Supports the local
backend the XCUITest suite seeds against.
