`Toolbox:` Migrate all Dialogues in Toolbox

[martineckardt]

Currently we have two different Modal components in the Toolbox: Shadcn and react-alert-dialog. Migrate all to Shadcn.

Remove this: https://github.com/ava-labs/builders-hub/blob/master/toolbox/src/components/AlertDialog.tsx

Use this:

builders-hub/toolbox/src/components/ConnectWallet/PChainFaucetButton.tsx

Line 82 in f004ec2

<AlertDialog open={isAlertDialogOpen} onOpenChange={setIsAlertDialogOpen}>
