Web frontend using WASM added

[greenlonk]

This pull request introduces several significant changes to the project, including adding new dependencies, updating the Dockerfile for better build and deployment processes, creating a new HTML file for the frontend, and implementing the frontend logic using Yew. The most important changes are highlighted below:

Dependency Additions:

• Added new dependencies in Cargo.toml for yew, wasm-bindgen, and web-sys to support the frontend web application. (Cargo.toml Cargo.tomlR25-R27)

Dockerfile Update:

• Updated the Dockerfile to use a multi-stage build process with Rust for building the project and Node.js for serving the built files. This change includes installing wasm-pack and using http-server for serving the application. (Dockerfile DockerfileL1-R35)

Frontend Implementation:

• Created a new index.html file to serve as the entry point for the web application, including basic styling and a script to initialize and run the Yew app. (index.html index.htmlR1-R61)
• Implemented the frontend logic in src/frontend_web.rs using Yew, including components for generating and validating product keys. (src/frontend_web.rs src/frontend_web.rsR1-R92)

Module Integration:

• Integrated the new frontend_web module into the main library by updating src/lib.rs to include and export the run_app function. (src/lib.rs src/lib.rsR19-R21)
