feat(geschichte): JourneyItem CRUD API — append, updateNote, delete, reorder (#751) (#788)
## Summary

Implements the backend JourneyItem CRUD API on top of the data model from #750, building towards the full Lesereisen feature (#751).

**Completed in this PR:**
- `jackson-databind-nullable` 0.2.6 + `JacksonConfig` (`@Bean Module`) for three-way PATCH semantics (`JsonNullable`)
- `AuditKind`: `JOURNEY_ITEM_ADDED`, `JOURNEY_ITEM_REMOVED`, `JOURNEY_ITEMS_REORDERED` (last is rollup-eligible)
- `ErrorCode`: `JOURNEY_ITEM_NOT_FOUND`, `JOURNEY_ITEM_POSITION_CONFLICT`
- V73 migration: `UNIQUE (geschichte_id, position) DEFERRABLE INITIALLY DEFERRED` + `CHECK (position > 0)` on `journey_items`
- `JourneyItemConstraintsTest`: verifies deferrable flag via `pg_constraint` query; position check; duplicate position rejection (3 passing tests)
- Read models: `DocumentSummary`, `JourneyItemView`, `GeschichteView` (with `AuthorView` to prevent AppUser email leak)
- `DocumentService.getSummaryById` — lean lookup without tag-color resolution
- `JourneyItemRepository`: extended with `findByGeschichteIdOrderByPosition`, `findByIdAndGeschichteId` (IDOR-safe), `findIdsByGeschichteId`, `findMaxPositionByGeschichteId`, `countByGeschichteId`
- DTOs: `JourneyItemCreateDTO`, `JourneyItemUpdateDTO` (`JsonNullable<String> note`), `JourneyReorderDTO`

**Still in progress (WIP):**
- `JourneyItemService` — `append`, `updateNote`, `delete`, `reorder`, `toSummary`, `toView` (Task 6)
- `GeschichteService.getById` → returns `GeschichteView` (Task 7)
- New endpoints on `GeschichteController` + slice tests (Task 8)
- Frontend error codes + i18n + `npm run generate:api` (Task 9)

## Commits

- `0b177247` feat(config): add jackson-databind-nullable for JsonNullable PATCH DTO support
- `408ae334` feat(audit,error): add JourneyItem AuditKind values and ErrorCodes
- `7b06c3ad` feat(migration): V73 adds UNIQUE DEFERRABLE and CHECK position > 0 on journey_items
- `160ca1c3` feat(geschichte): add DocumentSummary, JourneyItemView, GeschichteView read models
- `2ad5c36e` feat(geschichte): extend JourneyItemRepository and add item DTOs

## Test plan

- [ ] `./mvnw test -Dtest=JourneyItemConstraintsTest` — all 3 constraint tests pass
- [ ] `./mvnw clean package -DskipTests` — builds clean after remaining tasks are merged
- [ ] Frontend: `npm run generate:api` after Task 9 endpoint additions

Familienarchiv

Familienarchiv is a private web application for digitising, organising, and searching a family document collection — letters, postcards, and photographs from 1899 to 1950. Family members upload scans, transcribe handwritten text (Kurrent/Sütterlin), and read the archive from any device.


Subsystems

  • frontend/ — SvelteKit 2 / Svelte 5 / TypeScript / Tailwind 4 web app (server-side rendered)
  • backend/ — Spring Boot 4 (Java 21) REST API; handles documents, persons, search, and user management
  • ocr-service/ — Python FastAPI microservice for OCR and handwritten text recognition (HTR); single-node by design — see ADR-001. Not part of the default dev stack (see Quick start below)
  • infra/ — Gitea Actions CI/CD config; future home for infrastructure-as-code
  • scripts/ — operational and data-pipeline helpers (reset-db.sh, clean-e2e-data.sh, import scripts)

Quick start

Prerequisites: Java 21, Node 24, Docker with the docker compose plugin (V2).

1. Configure environment

cp .env.example .env
# The defaults in .env.example work for local development without changes.

2. Start infrastructure

# Starts PostgreSQL, MinIO (object storage), and Mailpit (dev mail catcher)
docker compose up -d db minio mailpit

3. Start the backend

cd backend
./mvnw spring-boot:run
# Starts on http://localhost:8080
# API docs (dev profile, auto-enabled): http://localhost:8080/v3/api-docs

4. Start the frontend

cd frontend
npm install
npm run dev
# Starts on http://localhost:5173

Open http://localhost:5173 — you should see the Familienarchiv login screen.

Default development credentials:

# local dev only — change before any network-exposed deployment
Email:    admin@familyarchive.local
Password: admin123

Development setup only. The default docker compose config exposes the database port and uses root MinIO credentials. Do not connect this to a network without first reading docs/DEPLOYMENT.md (coming: DOC-5, #399).

Running the full stack via Docker (optional)

To run everything including the backend and frontend in containers:

docker compose up -d

Note: the OCR service (ocr-service/) builds its Docker image locally and downloads ~6 GB of ML models on first start. Expect 3060 minutes on a first run. The rest of the stack starts independently; OCR can be excluded with --scale ocr-service=0 on memory-constrained machines (requires ≥ 12 GB RAM).
