refactor(exceptions): RFC 7807 Problem Details, ResourceBundle i18n, and error factory pattern (#4791)
# Description of Changes

Implemented RFC 7807 problem-details standard to provide consistent,
structured error responses across the application. All exceptions now
flow through a centralized `GlobalExceptionHandler` with tailored
handlers for password-protected files, corruption, validation, and
Spring framework errors. Every response includes localized `errorCode`,
contextual hints, actionable guidance, timestamps, and request paths.

**Key improvements:**
- Unified error handling prevents inconsistent response formats across
services
- Localized error messages support multiple languages at runtime
- Error context (hints, actionRequired field) improves user experience
- Structured metadata enables programmatic error handling on client side

Reference:
https://www.baeldung.com/spring-boot-return-errors-problemdetail

### Exception Handling

- Centralized all exception handling in `GlobalExceptionHandler` with
specific handlers for password protection, file corruption, validation
errors, and Spring exceptions
- Refactored `ExceptionUtils` to generate consistent `ProblemDetail`
responses with error metadata
- Introduced `ErrorCode` enum to centralize error identification and
metadata (supports localization)
- Added helper methods for creating standardized exceptions across
services

### Implementation Details

- **Replaced generic exceptions** with `ExceptionUtils` methods across
utility classes (`CbrUtils`, `CbzUtils`, `PdfToCbrUtils`,
`EmlProcessingUtils`, `ImageProcessingUtils`) for consistent error
handling of invalid formats, empty files, and missing resources
- **Improved method signatures** in `JobExecutorService` and
`AutoJobAspect` by explicitly declaring thrown exceptions
- **Refined job execution error handling** by removing unnecessary catch
blocks in synchronous execution, allowing exceptions to propagate to the
centralized handler
- **Enhanced error messages** for unsupported formats (e.g., RAR5
limitations, PDF-to-CBR constraints) with clearer user guidance

### Response Format

All errors now include:
- `errorCode`: Machine-readable error identifier (localized at runtime)
- `title`: Localized error title
- `detail`: Context-specific error message
- `hints`: Array of actionable suggestions
- `actionRequired`: Boolean flag indicating if user action is needed
- `timestamp`: Error occurrence time
- `path`: Request path where error occurred

**Error examples shown in PR include:** corrupt files, invalid
passwords, unsupported formats (RAR5), missing images, OOM conditions,
and invalid HTML

### Why This Change

- Eliminates ad-hoc error handling patterns scattered across services
- Provides actionable guidance instead of technical stack traces
- Supports error messages in multiple languages without code changes
- Aligns with RFC 7807, improving API interoperability
- Error context reduces time to diagnose issues

chore(cucumber): add create_pdf_with_black_boxes and convert-pdf-to-image outline; remove duplicate split-pdf-by-sections (#3937)
# Description of Changes

- **What was changed**  
- Introduced `create_pdf_with_black_boxes` helper function in
`environment.py` for generating test PDFs with occluded content.
- Added **Scenario Outline: Convert PDF to image** to
`conversion.feature` to validate PDF→image conversion workflows.
- Removed the duplicate **Scenario Outline: split-pdf-by-sections with
different parameters** from `general.feature`.

- **Why the change was made**  
- To enable testing of blacked-out content scenarios and ensure our
suite covers image conversion.
- To eliminate redundant tests and keep the feature files DRY and
maintainable.

Improve Type Safety and OpenAPI Schema for PDF API Controllers and Models (#3470)
# Description of Changes

- **What was changed**  
- Updated controller methods to use strongly‐typed primitives (`int`,
`long`, `boolean`) instead of `String` for numeric and boolean
parameters, eliminating calls to `Integer.parseInt`/`Long.parseLong` and
improving null‐safety (`Boolean.TRUE.equals(...)`).
- Enhanced all API request model classes with richer Swagger/OpenAPI
annotations: added `requiredMode`, `defaultValue`, `allowableValues`,
`format`, `pattern`, and tightened schema descriptions for all fields.
- Refactored HTML form templates for “Remove Blank Pages” to include
`min`, `max`, and `step` attributes on numeric inputs, matching the
updated validation rules.

- **Why the change was made**  
- **Type safety & robustness**: Shifting from `String` to native types
prevents runtime parsing errors, simplifies controller logic, and makes
default values explicit.
- **Better API documentation & validation**: Enriching the Swagger
annotations ensures generated docs accurately reflect required fields,
default values, and permitted ranges, which improves client code
generation and developer experience.
- **Consistency across codebase**: Aligning all request models and
controllers enforces a uniform coding style and reduces bugs.

[Test PR] Desktop fix and unoconv to unoserver (#2971)
# Description of Changes

This pull request includes several updates to the Docker configuration
and Java application UI scaling. The changes enhance environment
variable management, dependency installation, and UI responsiveness to
different screen sizes.

### Docker Configuration Updates:
* Added new environment variables `STIRLING_PDF_DESKTOP_UI`,
`PYTHONPATH`, `UNO_PATH`, and `URE_BOOTSTRAP` to `Dockerfile` and
`Dockerfile.fat` to improve the configuration and integration of the
LibreOffice environment.

* Updated the `CMD` instruction in `Dockerfile` and `Dockerfile.fat` to
run both the Java application and `unoserver` simultaneously.
[[1]](diffhunk://#diff-dd2c0eb6ea5cfc6c4bd4eac30934e2d5746747af48fef6da689e85b752f39557L87-R96)

* Modified the `RUN` instruction to include additional Python
dependencies and setup a virtual environment.

### Workflow Enhancements:
* Added `STIRLING_PDF_DESKTOP_UI` environment variable to the GitHub
Actions workflows (`PR-Demo-Comment.yml` and `push-docker.yml`) to
ensure consistent environment settings.
[[1]](diffhunk://#diff-145fe5c0ed8c24e4673c9ad39800dd171a2d0a2e8050497cff980fc7e3a3df0dR106)

### Java Application UI Scaling:
* Introduced `UIScaling` utility to dynamically adjust the size of UI
components based on screen resolution in `DesktopBrowser` and
`LoadingWindow` classes.
[[1]](diffhunk://#diff-dff83b0fe53cba8ee80dc8cee96b9c2bfec612ec1f2c636ebdf22dedb36671e8L218-R219)

* Improved the loading of icons by using the `UIScaling` utility for
better visual quality.
