# Description of Changes
This pull request introduces a new SSRF (Server-Side Request Forgery)
protection mechanism for URL handling in the application. Key changes
include adding a dedicated `SsrfProtectionService`, integrating
SSRF-safe policies into HTML sanitization, and extending application
settings to support configurable URL security options.
### SSRF Protection Implementation:
* **`SsrfProtectionService`**: Added a new service to handle SSRF
protection with configurable levels (`OFF`, `MEDIUM`, `MAX`) and checks
for private networks, localhost, link-local addresses, and cloud
metadata endpoints
(`app/common/src/main/java/stirling/software/common/service/SsrfProtectionService.java`).
### Application Configuration Enhancements:
* **`ApplicationProperties`**: Introduced a new `Html` configuration
class with nested `UrlSecurity` settings, allowing fine-grained control
over URL security, including allowed/blocked domains and internal TLDs
(`app/common/src/main/java/stirling/software/common/model/ApplicationProperties.java`).

* **`settings.yml.template`**: Updated the configuration template to
include the new `html.urlSecurity` settings, enabling users to customize
SSRF protection behavior
(`app/core/src/main/resources/settings.yml.template`).
### HTML Sanitization Updates:
* **`CustomHtmlSanitizer`**: Integrated SSRF-safe URL validation into
the HTML sanitizer by using the `SsrfProtectionService`. Added a custom
policy for validating `img` tags' `src` attributes
(`app/common/src/main/java/stirling/software/common/util/CustomHtmlSanitizer.java`).

# Description of Changes
- **What was changed**
- Relocated `png_to_webp.py` and `split_photos.py` from `scripts/` to
`app/core/src/main/resources/static/python/`.
- Updated `.github/labeler-config-srvaroa.yml` and
`.pre-commit-config.yaml` to include the new script directory in their
file-matching patterns.
- Added `GeneralUtils.extractScript(String scriptName)` to load Python
scripts from the classpath (`static/python/`), extract them into a
temporary directory at runtime, and return the filesystem path.
- **Why the change was made**
- To fix the Internal Server Error caused by missing script files at
their old locations.
- Ensure the Python helper scripts are packaged inside the JAR/WAR and
reliably accessible when the application runs.
- Only local installations were affected

# Description of Changes
- **What was changed:**
- Renamed top-level directories: `stirling-pdf` → `app/core`, `common` →
`app/common`, `proprietary` → `app/proprietary`.
- Updated all path references in `.gitattributes`, GitHub workflows
(`.github/workflows/*`), scripts (`.github/scripts/*`), `.gitignore`,
Dockerfiles, license files, and template settings to reflect the new
structure.
- Added a new CI job `check-generateOpenApiDocs` to generate and upload
OpenAPI documentation.
- Removed redundant `@Autowired` annotations from `TempFileShutdownHook`
and `UnlockPDFFormsController`.
- Minor formatting and comment adjustments in YAML templates and
resource files.
- **Why the change was made:**
- To introduce a clear `app/` directory hierarchy for core, common, and
proprietary modules, improving organization and maintainability.
- To ensure continuous integration and Docker builds continue to work
seamlessly with the reorganized structure.
- To automate OpenAPI documentation generation as part of the CI
pipeline.
