Test case:

Both Instant and Secure have similar balance.

Paste an onchain Bitcoin bip21 with an amount higher than what is available in both wallets.

Result:

Instant Wallet is selected and we show, not enough balance. If the amount is updated to a smaller amount within balance, send is still disabled.

Expected:

Secure wallet should be selected and if the amount is changed to something less, Send button should be enabled

If a wallet is selected and a user attempts send from a specific wallet page - wallet selection should not take place - currently it does.

Wallet selection should only happen when a user attempts to send from the homepage.
