# Description of Changes
This pull request introduces several enhancements and new features,
primarily focused on improving API documentation support, expanding
backend functionality, and adding new frontend tools. Key changes
include the integration of Swagger API documentation, the addition of a
new `UIDataController` for backend data handling, and updates to the
frontend to include a Swagger UI tool.
### Backend Enhancements:
* **Swagger API Documentation Integration**:
- Added support for dynamically configuring Swagger servers using the
`SWAGGER_SERVER_URL` environment variable in `OpenApiConfig`
(`[app/core/src/main/java/stirling/software/SPDF/config/OpenApiConfig.javaR54-L63](diffhunk://#diff-6080fb3dc14efc430c9de1bf9fa4996a23deebc14230dde7788949b2c49cca68R54-L63)`).
- Imported necessary Swagger dependencies
(`[app/core/src/main/java/stirling/software/SPDF/config/OpenApiConfig.javaR13](diffhunk://#diff-6080fb3dc14efc430c9de1bf9fa4996a23deebc14230dde7788949b2c49cca68R13)`).
- Updated `nginx.conf` to proxy Swagger-related requests to the backend
(`[docker/frontend/nginx.confR55-R92](diffhunk://#diff-6d35fafb4405bd052c6d5e48bd946bcef7c77552a74e1b902de45e85eee09aceR55-R92)`).
* **New `UIDataController`**:
- Introduced a new controller (`UIDataController`) to serve React UI
data, including endpoints for home data, licenses, pipeline
configurations, signature data, and OCR data
(`[app/core/src/main/java/stirling/software/SPDF/controller/api/UIDataController.javaR1-R301](diffhunk://#diff-3e7063d4e921c7b9e6eedfcad0e535ba3eff68476dcff5e6f28b00c388cff646R1-R301)`).
* **Endpoint Handling**:
- Modified `ConfigController` to include explicit parameter naming for
better clarity in API requests
(`[app/core/src/main/java/stirling/software/SPDF/controller/api/misc/ConfigController.javaL113-R120](diffhunk://#diff-43d19d45ae547fd79090596c06d58cb0eb7f722ed43eb4da59f9dec39f6def6eL113-R120)`).
### Frontend Enhancements:
* **Swagger UI Tool**:
- Added a new tool definition (`swagger`) in `useToolManagement.tsx`,
with an icon and lazy-loaded component
(`[frontend/src/hooks/useToolManagement.tsxR30-R38](diffhunk://#diff-57f8a6b3e75ecaec10ad445b01afe8fccc376af6f8ad4d693c68cf98e8863273R30-R38)`).
- Implemented the `SwaggerUI` component to open the Swagger
documentation in a new tab
(`[frontend/src/tools/SwaggerUI.tsxR1-R18](diffhunk://#diff-ca9bdf83c5d611a5edff10255103d7939895635b33a258dd77db6571da6c4600R1-R18)`).
* **Localization Updates**:
- Updated English (US and GB) translation files to include
Swagger-related strings
(`[[1]](diffhunk://#diff-14c707e28788a3a84ed5293ff6689be73d4bca00e155beaf090f9b37c978babbR578-R581)`,

### Workflow Updates:
* **Environment Variable Additions**:
- Added `SWAGGER_SERVER_URL` to the `PR-Auto-Deploy-V2.yml` and
`deploy-on-v2-commit.yml` workflows for configuring Swagger server URLs
(`[[1]](diffhunk://#diff-931fcb06ba030420d7044dde06465ad55b4e769a9bd374dcd6a0c76f79a5e30eR320)`,
