Flash wallet: improve wallet connection experience

[Dayvvo]

there is a "Get one here" button on the connectors list that leads to nwc connected wallets that a user can download. I would like to include the flash wallet as one of these options. Also on the Screen that displays the QR code, I would also like to improve connection instructions for the flash wallet and also provide a small helper text that beginners get setup with a wallet easier

@rolznz let me know what you think about this

@stackingsaunter @reneaaron could you please review the change? maybe flash can be shown next to Alby Hub as another self-custodial option?

@rolznz any update on this?

@Dayvvo sorry for the delay. I've bumped @stackingsaunter

@stackingsaunter rizful could also be added to the bottom row
