Merge branch 'V2' into unified_docker

# Description of Changes

This pull request removes unnecessary imports of the default React
object from multiple frontend files. The changes help clean up the
codebase by only importing specific React hooks where needed, rather
than importing the entire React object.

**Code cleanup and import optimization:**

* Removed default `React` imports from component files, retaining only
the necessary React hooks (such as `useEffect`, `useState`, `useMemo`,
etc.) in files like `FileEditor.tsx`, `FullscreenToolList.tsx`,
`ToolPanel.tsx`, `PageNumberPreview.tsx`, `AdjustContrastPreview.tsx`,
`AutomationRun.tsx`, `LocalEmbedPDFWithAnnotations.tsx`,
`ToolRegistryProvider.tsx`, `useTranslatedToolRegistry.tsx`, and
`AdjustContrast.tsx`.

+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>]

+
+---
+
+## Docker Compose Examples
+
+### Example 1: All-in-One (MODE=BOTH)
+
+**File:** `docker/compose/docker-compose-unified-both.yml`
+
+```yaml
+services:
+  stirling-pdf:
+    image: stirlingtools/stirling-pdf:unified
+    ports:
+      - "8080:8080"
+    volumes:
+      - ./data:/usr/share/tessdata:rw
+      - ./config:/configs:rw
+    environment:
+      MODE: BOTH
+    restart: unless-stopped
+```
+
+### Example 2: Separate Frontend & Backend
+
+**File:** `docker/compose/docker-compose-unified-frontend.yml`
+
+```yaml
+services:
+  backend:
+    image: stirlingtools/stirling-pdf:unified
+    ports:
+      - "8081:8080"
+    environment:
+      MODE: BACKEND
+    volumes:
+      - ./data:/usr/share/tessdata:rw
+      - ./config:/configs:rw
+
+  frontend:
+    image: stirlingtools/stirling-pdf:unified
+    ports:
+      - "8080:8080"
+    environment:
+      MODE: FRONTEND
+      VITE_API_BASE_URL: http://backend:8080
+    depends_on:
+      - backend
+```
+
+### Example 3: Backend API Only
+
+**File:** `docker/compose/docker-compose-unified-backend.yml`
+
+```yaml
+services:
+  stirling-pdf-api:
+    image: stirlingtools/stirling-pdf:unified
+    ports:
+      - "8080:8080"
+    environment:
+      MODE: BACKEND
+    volumes:
+      - ./data:/usr/share/tessdata:rw
+      - ./config:/configs:rw
+    restart: unless-stopped
+```
+
+---
+
+## Building the Image
+
+```bash
+# From repository root
+docker build -t stirlingtools/stirling-pdf:unified -f docker/Dockerfile.unified .
+```
+
+### Build Arguments
+
+| Argument | Description |
+|----------|-------------|
+| `VERSION_TAG` | Version tag for the image |
+
+Example:
+```bash
+docker build \
+  --build-arg VERSION_TAG=v1.0.0 \
+  -t stirlingtools/stirling-pdf:unified \
+  -f docker/Dockerfile.unified .
+```
+
+---
+
+## Use Cases
+
+### 1. Simple Deployment (MODE=BOTH)
+- **Best for:** Personal use, small teams, simple deployments
+- **Pros:** Single container, easy setup, minimal configuration
+- **Cons:** Frontend and backend scale together
+
+### 2. Scaled Frontend (MODE=FRONTEND + BACKEND)
+- **Best for:** High traffic, need to scale frontend independently
+- **Pros:** Scale frontend containers separately, CDN-friendly
+- **Example:**
+  ```yaml
+  services:
+    backend:
+      image: stirlingtools/stirling-pdf:unified
+      environment:
+        MODE: BACKEND
+      deploy:
+        replicas: 1
+
+    frontend:
+      image: stirlingtools/stirling-pdf:unified
+      environment:
+        MODE: FRONTEND
+        VITE_API_BASE_URL: http://backend:8080
+      deploy:
+        replicas: 5  # Scale frontend independently
+  ```
+
+### 3. API-Only (MODE=BACKEND)
+- **Best for:** Headless deployments, custom frontends, API integrations
+- **Pros:** Minimal resources, no nginx overhead
+- **Example:** Use with external frontend or API consumers
+
+### 4. Multi-Backend Setup
+- **Best for:** Load balancing, high availability
+- **Example:**
+  ```yaml
+  services:
+    backend-1:
+      image: stirlingtools/stirling-pdf:unified
+      environment:
+        MODE: BACKEND
+
+    backend-2:
+      image: stirlingtools/stirling-pdf:unified
+      environment:
+        MODE: BACKEND
+
+    frontend:
+      image: stirlingtools/stirling-pdf:unified
+      environment:
+        MODE: FRONTEND
+        VITE_API_BASE_URL: http://load-balancer:8080
+  ```
+
+---
+
+## Port Configuration
+
+All modes use **port 8080** by default:
+
+- **MODE=BOTH**: Nginx listens on 8080, proxies to backend on internal 8081
+- **MODE=FRONTEND**: Nginx listens on 8080
+- **MODE=BACKEND**: Spring Boot listens on 8080
+
+**Expose port 8080** in all configurations:
+```yaml
+ports:
+  - "8080:8080"
+```
+
+---
+
+## Health Checks
+
+### MODE=BOTH and MODE=BACKEND
+```yaml
+healthcheck:
+  test: ["CMD-SHELL", "curl -f http://localhost:8080/api/v1/info/status || exit 1"]
+  interval: 30s
+  timeout: 10s
+  retries: 3
+```
+
+### MODE=FRONTEND
+```yaml
+healthcheck:
+  test: ["CMD-SHELL", "curl -f http://localhost:8080/ || exit 1"]
+  interval: 30s
+  timeout: 10s
+  retries: 3
+```
+
+---
+
+## Troubleshooting
+
+### Check logs
+```bash
+docker logs stirling-pdf-container
+```
+
+Look for the startup banner:
+```
+===================================
+Stirling-PDF Unified Container
+MODE: BOTH
+===================================
+```
+
+### Invalid MODE error
+```
+ERROR: Invalid MODE 'XYZ'. Must be BOTH, FRONTEND, or BACKEND
+```
+**Fix:** Set `MODE` to one of the three valid values.
+
+### Frontend can't connect to backend (MODE=FRONTEND)
+**Check:**
+1. `VITE_API_BASE_URL` points to correct backend URL
+2. Backend container is running and accessible
+3. Network connectivity between containers
+
+### Backend not starting (MODE=BOTH or BACKEND)
+**Check:**
+1. Sufficient memory allocated (4GB recommended)
+2. Java heap size (`JAVA_CUSTOM_OPTS`)
+3. Volume permissions for `/tmp/stirling-pdf`
+
+---
+
+## Migration Guide
+
+### From Separate Containers → MODE=BOTH
+
+**Before:**
+```yaml
+services:
+  frontend:
+    image: stirlingtools/stirling-pdf:frontend
+    ports: ["80:80"]
+
+  backend:
+    image: stirlingtools/stirling-pdf:backend
+    ports: ["8080:8080"]
+```
+
+**After:**
+```yaml
+services:
+  stirling-pdf:
+    image: stirlingtools/stirling-pdf:unified
+    ports: ["8080:8080"]
+    environment:
+      MODE: BOTH
+```
+
+### From Legacy → MODE=BACKEND
+```yaml
+services:
+  stirling-pdf:
+    image: stirlingtools/stirling-pdf:latest
+    ports: ["8080:8080"]
+```
+
+**Becomes:**
+```yaml
+services:
+  stirling-pdf:
+    image: stirlingtools/stirling-pdf:unified
+    ports: ["8080:8080"]
+    environment:
+      MODE: BACKEND
+```
+
+---
+
+## Performance Tuning
+
+### MODE=BOTH
+```yaml
+environment:
+  JAVA_CUSTOM_OPTS: "-Xmx4g -XX:MaxRAMPercentage=75"
+  BACKEND_INTERNAL_PORT: 8081
+deploy:
+  resources:
+    limits:
+      memory: 4G
+    reservations:
+      memory: 2G
+```
+
+### MODE=FRONTEND (Lightweight)
+```yaml
+deploy:
+  resources:
+    limits:
+      memory: 512M
+    reservations:
+      memory: 256M
+```
+
+### MODE=BACKEND (Heavy Processing)
+```yaml
+environment:
+  JAVA_CUSTOM_OPTS: "-Xmx8g"
+deploy:
+  resources:
+    limits:
+      memory: 10G
+    reservations:
+      memory: 4G
+```
+
+---
+
+## Security Considerations
+
+1. **MODE=BOTH**: Backend not exposed externally (runs on internal port)
+2. **MODE=BACKEND**: API exposed directly - consider API authentication
+3. **MODE=FRONTEND**: Only serves static files - minimal attack surface
+
+Enable security features:
+```yaml
+environment:
+  DOCKER_ENABLE_SECURITY: "true"
+  SECURITY_ENABLELOGIN: "true"
+```
