tools/local-dev: docker-compose stack for UI development

Adds tools/local-dev/ with postgres + redis + mailpit + backend + gateway plus a Make wrapper, so `make -C tools/local-dev up` brings the full authenticated stack online and `pnpm -C ui/frontend dev` talks to it directly. The committed `.env.development` already points at the stack and pins the matching gateway response public key from the dev keypair under tools/local-dev/keys/. The backend ships a new opt-in env, BACKEND_AUTH_DEV_FIXED_CODE (`tools/local-dev/.env` defaults it to 123456). When set, ConfirmEmailCode accepts that literal in addition to the real bcrypt-verified code; SendEmailCode still queues a real email so Mailpit captures the issued code at http://localhost:8025/, and both paths coexist. The override is rejected as non-six-digit by config validation and emits a loud warning at backend startup. The local-dev Dockerfiles mirror backend/Dockerfile and gateway/Dockerfile but switch the runtime stage to alpine so docker-compose healthchecks can wget /healthz; the gateway Dockerfile additionally copies ui/core/ into the build context because gateway/go.mod's `replace galaxy/core => ../ui/core` is required to compile the gateway main. Smoke tested: - `make -C tools/local-dev up` boots all five services to healthy. - send-email-code + confirm-email-code with code=123456 returns a device_session_id; a real code in Mailpit also redeems successfully. - `pnpm test` 14/14, `pnpm exec playwright test` 44/44. - `go test ./backend/internal/config/...` green. Docs: tools/local-dev/README.md, tools/local-dev/keys/README.md, new "Local development stack" section in ui/docs/testing.md, and a short pointer in ui/README.md.
