Feature Request: Add ability to export view only wallet

[deverickapollo]

Hi team,

I’d like to request a feature that enables users to create and export a view-only wallet directly from the Cake Wallet app.

Use Case:

A Cake Wallet user wants to set up a BTCPay Server store to accept Monero payments. To do this, the server requires a view-only wallet, consisting of:
• the main wallet file
• the .keys file (with only the view key, no spend key)

Currently, Cake Wallet doesn’t provide a way to generate and export this type of wallet. Adding this feature would allow users to generate a view-only wallet for receiving XMR payments.
