update

## Summary
- add a dedicated edit table of contents tool to the React UI, complete
with bookmark editor, import/export actions, and parameter handling
- register the tool in the translated registry and extend the English
translations with the new strings
- wire up the backend endpoints through a new operation hook and
form-data serialization helpers

## Testing
- ./gradlew build

+Author: Ludy87
+Description: This script processes JSON translation files for localization checks. It compares translation files in a branch with
+a reference file to ensure consistency. The script performs two main checks:
+1. Verifies that the number of translation keys in the translation files matches the reference file.
+2. Ensures that all keys in the translation files are present in the reference file and vice versa.
+
+The script also provides functionality to update the translation files to match the reference file by adding missing keys and
+adjusting the format.
+
+Usage:
+    python check_language_json.py --reference-file <path_to_reference_file> --branch <branch_name> [--actor <actor_name>] [--files <list_of_changed_files>]
+"""
+# Sample for Windows:
+# python .github/scripts/check_language_json.py --reference-file frontend/public/locales/en-GB/translation.json --branch "" --files frontend/public/locales/de-DE/translation.json frontend/public/locales/fr-FR/translation.json

+            ### Description of Changes
+
+            This Pull Request was automatically generated to synchronize updates to translation files and documentation for the **V2 branch**. Below are the details of the changes made:
+
+            #### **1. Synchronization of Translation Files**
+            - Updated translation files (`frontend/public/locales/*/translation.json`) to reflect changes in the reference file `en-GB/translation.json`.
+            - Ensured consistency and synchronization across all supported language files.
+            - Highlighted any missing or incomplete translations.
+
+            #### **2. Update README.md**
+            - Generated the translation progress table in `README.md`.
+            - Added a summary of the current translation status for all supported languages.
+            - Included up-to-date statistics on translation coverage.
+
+            #### **Why these changes are necessary**
+            - Keeps translation files aligned with the latest reference updates.
+            - Ensures the documentation reflects the current translation progress.

 The newly introduced feature enhances the application with robust database backup and import capabilities. This feature is designed to ensure data integrity and provide a straightforward way to manage database backups. Here's how it works:
 
 1. Automatic Backup Creation
-   - The system automatically creates a database backup every day at midnight. This ensures that there is always a recent backup available, minimizing the risk of data loss.
+   - The system automatically creates a database backup on a configurable schedule (default: daily at midnight via `system.databaseBackup.cron`). This ensures that there is always a recent backup available, minimizing the risk of data loss.
 2. Manual Backup Export
    - Admin actions that modify the user database trigger a manual export of the database. This keeps the backup up-to-date with the latest changes and provides an extra layer of data security.
 3. Importing Database Backups
