# 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.

# Description of Changes
This pull request includes several changes primarily focused on
improving configuration management, removing deprecated methods, and
updating paths for external dependencies. The most important changes are
summarized below:
### Configuration Management Improvements:
* Added a new `RuntimePathConfig` class to manage dynamic paths for
operations and pipeline configurations
(`src/main/java/stirling/software/SPDF/config/RuntimePathConfig.java`).
* Removed the `bookAndHtmlFormatsInstalled` bean and its associated
logic from `AppConfig` and `EndpointConfiguration`
(`src/main/java/stirling/software/SPDF/config/AppConfig.java`,
`src/main/java/stirling/software/SPDF/config/EndpointConfiguration.java`).

### External Dependency Path Updates:
* Updated paths for `weasyprint` and `unoconvert` in
`ExternalAppDepConfig` to use values from `RuntimePathConfig`
(`src/main/java/stirling/software/SPDF/config/ExternalAppDepConfig.java`).

### Minor Adjustments:
* Corrected a typo from "Unoconv" to "Unoconvert" in
`EndpointConfiguration`
(`src/main/java/stirling/software/SPDF/config/EndpointConfiguration.java`).
