Add WebApp example demonstrating IBAN validation and generation

[rorychatt]

Summary

This PR adds a new interactive web application example (examples/WebApp) that demonstrates IBAN validation and generation using IbanNet integrated with Ivy Framework. This example showcases how to build a modern, interactive web UI entirely in C# using IbanNet's core features.

What's Included

• Interactive IBAN Management Application: A full-featured web app that allows users to:

  • Validate IBAN numbers with real-time feedback
  • Generate test IBANs for any supported country (100+ countries)
  • View detailed IBAN structure analysis including country information, BBAN, bank identifiers, and SEPA membership status
  • Copy IBAN numbers in multiple formats (Electronic, Print, Obfuscated)

• Technical Implementation:

  • Uses IbanValidator for robust validation
  • Implements IbanGenerator for test IBAN creation
  • Leverages IbanParser for detailed structure analysis
  • Integrates SwiftRegistryProvider and WikipediaRegistryProvider for comprehensive country data
  • Built with Ivy Framework for a modern, responsive UI with card-based layout

Why This Example?

This example complements the existing examples (AspNetCore, AutoMapper, GenerateIbans, LimitCountries) by providing:

• A modern web application demonstration using a cutting-edge framework
• Interactive UI showcasing IbanNet's validation and parsing capabilities
• A practical tool for developers to test and validate IBAN numbers
• An example of integrating IbanNet with modern web frameworks

Requirements

• .NET 9.0 SDK or later
• Ivy Framework (automatically restored via NuGet)

How to Run

cd examples/WebApp
dotnet restore
dotnet watchThen open your browser to the URL shown in the terminal (typically http://localhost:5010).

Files Added

• examples/WebApp/ - Complete web application example
  • Program.cs - Application entry point
  • Apps/IbanNetDemoApp.cs - Main application UI and logic
  • GlobalUsings.cs - Global using statements
  • IbanNetExample.csproj - Project file with dependencies
  • README.md - Comprehensive documentation

Testing

The application has been tested with:

• Valid IBAN numbers from various countries
• Invalid IBAN numbers to verify error handling
• IBAN generation for multiple countries
• Real-time validation feedback

Hi there, I appreciate the effort but I don't believe it adds much value over the existing examples. And rather, I believe an example of this kind fits better in your own repository?
