[Request] Demonstrate standard browser wallet integration for IOTA trust framework products

## Description

As been proposed in this [Discord post](https://discord.com/channels/912718559954747442/1353999635890311239/1393332232004964372):

* In web applications using a browser wallet following the [wallet standard](https://github.com/wallet-standard/wallet-standard/) (i.e. IOTA Wallet or Nightly Wallet) will be more or less mandatory
* We need an example how to implement our [TransactionSigner](https://github.com/iotaledger/product-core/blob/main/bindings/wasm/iota_interaction_ts/src/bindings/wasm_transaction_signer.rs#L19) interface using these wallets

## Motivation
Demonstrate how to use IOTA trust framework products with standard browser wallets

## Requirements

Ideally:
- provide a Vercel app or a Cyprus test demonstrating how to implement this

Start by reading the TransactionSigner interface in bindings/wasm/iota_interaction_ts/src/bindings/wasm_transaction_signer.rs and the wallet-standard documentation linked in the issue. Build a Vercel app or Cyprus test showing how IOTA Wallet or Nightly Wallet can be used with the IOTA trust framework products, and consider the work done when the example demonstrates that integration.
