fix(import): align child-parent pedigree mapping by using name cell row for vertical alignment

Detailseite (Rennmausakte):
- Neugestaltung: Hero-Foto + Overlay, Schnellfakten-Pills, Karten-Sektionen,
  Charakter als Chips, getabte Fotos/Gesundheit/Gewicht.
- Eltern (Vater/Mutter) als Links; Charakter-Karte klappt bei Status
  Abgabe/Verstorben/Abgegeben ein (nur Zucht/Liebhaber offen).
- Gehege wird bei abgegebenen/verstorbenen Tieren ausgeblendet (Detail + Formular).

Listen:
- Infinite Scroll auf allen Listen (Rennmäuse, Würfe, Gehege, Verträge,
  Anfragen, Kontakte) via useInfiniteList/useInfiniteSentinel; stabile
  Sortierung mit id-Tiebreaker (keine doppelten Keys), Back-to-top-Button.
- Kontakte: Rolle-Filter (Züchter/Abnehmer) als Quick-Chips + Sticky-Header.

Zucht-Nachname:
- Namens-Anhängsel der Zucht in den Einstellungen + je Züchter-Kontakt
  (Backend-Spalten + Migration); eigene Tiere zeigen „Name + Suffix".
- „Eigene Zucht" ist die Standard-Herkunft neuer Tiere.

Weiteres:
- Gehege-Bilder: Upload/Galerie auf der Gehege-Detailseite (Backend
  EnclosurePhoto + Endpoints + Migration, geteilte Dateiablage).
- Toast-Rückmeldungen für alle Speichern-Aktionen.
- Checkboxen durch mobile-freundliche Toggle-Schalter ersetzt.

-- `gerbil-manager-web/` — React-Frontend (Vite + TypeScript), siehe `gerbil-manager-web/README.md`
+
-
+- `GerbilManagerWebAPI/` — ASP.NET Core backend (Swagger under `/swagger`)
-# Requirements
+- `gerbil-manager-web/` — React Frontend (Vite + TypeScript), see `gerbil-manager-web/README.md`
-Install ef:
+- `tools/import/` — Python import pipeline scripts and database schemas
-
+
-dotnet tool install --global dotnet-ef
+## Requirements
-
+To manage database migrations, install the EF Core CLI tool globally:
-# Used cmd´s
+```bash
-## Start containers
+dotnet tool install --global dotnet-ef
-docker compose up
+```
-## Create the initial database
+
-dotnet ef database update
+## Running the Application
-## Create an migration script
+To run the full stack (PostgreSQL database, WebAPI, and Frontend Vite app) in one command:
-dotnet ef migrations add <name>
+```bash
-
+dotnet run --project GerbilManager.AppHost
-## Docker
+```
-### force compose rebuild
+
-docker-compose build --no-cache
+---
-
+
-## Frontend (gerbil-manager-web)
+## 📥 Data Import & Normalization Pipeline
-cd gerbil-manager-web
+
-npm install
+The application features a Python-based import pipeline that compiles gerbil breeding records, lineage, photos, and contact information from source files (markdown logs, Excel spreadsheets, Word documents) into a unified JSON format, and ingests them into the PostgreSQL database.
-npm run dev
+
-
+### 1. Structure of the Pipeline
-
+
-TODO:
+*   **Source Data**: Located at `C:\Users\gulum\dev\Wurfchronik_Bilder` (contains markdown files, `.xlsx` pedigree trees, and detail logs).
-- Backup docker volume database 
+*   **Compilation**: [merge_and_resolve.py](file:///C:/Users/gulum/dev/GerbilManager/tools/import/merge_and_resolve.py) processes the source files, extracts breeding details, resolves lineage links, maps colors/genotypes, and normalizes contact names.
-- run "dotnet ef database update" if no database exist.
+*   **Normalization Mapping**: `merge_and_resolve.py` contains a `norm_map` dictionary of contact name normalizations. This maps various spelling variations and abbreviations to a single canonical name.
+
+### 2. How to Run the Import
+
+#### Automatic Way (All-in-One)
+The PowerShell script in `tools/import` boots the Aspire stack, waits for the API to become ready, and automatically triggers the ingest:
+```powershell
+powershell -ExecutionPolicy Bypass -File tools/import/run_app_and_import.ps1
+```
+
+#### Manual Way
+1.  **Recompile the import data**:
+    Run the compiler script from the root directory to parse raw sources and output a fresh `resolved_import.json`:
+    ```bash
+    python tools/import/merge_and_resolve.py
+    ```
+2.  **Ingest into the running database**:
+    Ensure the application is running, then send an HTTP `POST` request to the API:
+    ```bash
+    Invoke-RestMethod -Uri "http://localhost:5179/import/ingest-resolved" -Method Post
+    ```
+
+---
+
+## 👥 Contact Deduplication Workflow
+
+When the database is wiped and re-imported, you can detect and resolve duplicate contacts (e.g. spelling mistakes, initials vs full names) using the deduplication checklist workflow.
+
+### 1. Search for Duplicate Contacts
+You can run duplicate checks using two different similarity parameter models:
+*   **Round 1 (Clever matching on first 4 characters)**:
+    ```bash
+    python tools/import/find_duplicates_v5.py
+    ```
+    Creates: `tools/import/output/potential_duplicates_decision.md`
+*   **Round 2 (Broader matching on initials, matching last names, phones, or emails)**:
+    ```bash
+    python tools/import/find_duplicates_round2.py
+    ```
+    Creates: `tools/import/output/potential_duplicates_decision_round2.md`
+
+### 2. Fill out the Checklist
+Open the generated markdown checklist file and edit the checkboxes:
+*   **Combine/Merge**: Put an `x` in the checkbox `[x]` of the name you want to choose as the **canonical name**. Leave the checkboxes empty `[ ]` for any names you want to **merge into the canonical name**.
+*   **Standalone**: Put an `o` in the checkbox `[o]` of any name that should remain a separate, standalone contact.
+*   **New Name**: Put an `x` next to `Custom name:` and type your new desired name inside the backticks.
+*   **Keep all separate**: Leave all checkboxes in a Choice empty `[ ]`.
+
+*Example:*
+```markdown
+- [x] Max Mustermann   <-- canonical name
+- [ ] Max M.           <-- merges into Max Mustermann
+- [o] Moritz Mustermann <-- remains a separate standalone contact
+```
+
+### 3. Apply the Decisions
+Once you have saved your decisions in the checklist file, run the parser:
+```bash
+python tools/import/parse_decisions.py
+```
+This automatically parses your selections, resolves the merges, and updates the `norm_map` inside `merge_and_resolve.py` so they are **permanently saved** in the codebase.
+Run the compilation pipeline again to produce the final deduplicated import JSON:
+```bash
+python tools/import/merge_and_resolve.py
+```
