feat(stamp): add dynamic variables and templates for stamp text customization (#5546)
# Description of Changes

This pull request improves the PDF stamping feature, particularly the
text stamping functionality, by introducing dynamic variables, improving
formatting flexibility, and refining positioning logic. The changes
include backend support for dynamic stamp variables (such as date, time,
filename, and metadata), improvements to text layout and positioning,
updates to the API and frontend for usability, and localization
enhancements for user guidance.

**Dynamic Stamp Variables and Text Processing:**

* Added support for dynamic variables in stamp text (e.g., `@date`,
`@time`, `@page_number`, `@filename`, `@uuid`, and metadata fields),
including custom date formats and escaping for literal `@` symbols. This
is handled by the new `processStampText` method in
`StampController.java`.
* Implemented validation and formatting for custom date variables,
ensuring only safe formats are accepted and providing user-friendly
error messages for invalid formats.

**Text Layout and Positioning Improvements:**

* Refactored text and image stamp positioning: now calculates line
heights, block heights, and widths for multi-line stamps, and adjusts
placement logic for more accurate alignment (top, center, bottom) and
margins.
* Updated the default font size for stamps to 40pt and improved font
size handling in both backend and frontend, including validation for
positive values

**API and Method Signature Updates:**

* Extended method signatures to include additional context (such as page
index and filename) for more powerful variable substitution in stamps
**Frontend and Localization Enhancements:**

* Added comprehensive help text, variable descriptions, and template
examples to the UI, making it easier for users to understand and use
dynamic stamp variables.
* Improved accessibility and clarity in the stamp formatting UI by
disabling controls appropriately and providing clearer descriptions.

Getting Started with Create React App

This project was bootstrapped with Create React App.

Docker Setup

For Docker deployments and configuration, see the Docker README.

Available Scripts

In the project directory, you can run:

npm start

Runs the app in the development mode.
Open http://localhost:3000 to view it in your browser.

The page will reload when you make changes.
You may also see any lint errors in the console.

npm test

Launches the test runner in the interactive watch mode.
See the section about running tests for more information.

npm run build

Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.
Your app is ready to be deployed!

See the section about deployment for more information.

npm run eject

Note: this is a one-way operation. Once you eject, you can't go back!

If you aren't satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.

Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you're on your own.

You don't have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't customize it when you are ready for it.

Learn More

You can learn more in the Create React App documentation.

To learn React, check out the React documentation.

Tauri

In order to run Tauri, you first have to build the Java backend for Tauri to use.

macOS/Linux:

From the root of the repo, run:

./gradlew clean build
./scripts/build-tauri-jlink.sh

Windows

From the root of the repo, run:

gradlew clean build
scripts\build-tauri-jlink.bat

Testing the Bundled Runtime

Before building the full Tauri app, you can test the bundled runtime:

macOS/Linux:

./frontend/src-tauri/runtime/launch-stirling.sh

Windows:

frontend\src-tauri\runtime\launch-stirling.bat

This will start Stirling-PDF using the bundled JRE, accessible at http://localhost:8080

Dev

To run Tauri in development. Use the command in the frontend folder:

npm run tauri-dev

This will run the gradle runboot command and the tauri dev command concurrently, starting the app once both are stable.

Build

To build a deployment of the Tauri app. Use this command in the frontend folder:

npm run tauri-build

This will bundle the backend and frontend into one executable for each target. Targets can be set within the tauri.conf.json file.
