Closes: https://github.com/hicommonwealth/commonwealth/issues/6645

Description of Changes

• Added Welcome Onboard Modal, which is shown after a new user creates an account
• Added Personal Information Step in welcome onboard modal, this step requires the user to provide their username before this modal can be closed
• Added form validation and negative logical checks to the Personal Information Step
• Updated Checkbox to work with CWForm
• Fixed useWallets logic where new wallet signups, were not triggering the isNewlyCreated flag

• Add type='create-account' to <AuthModal/> instance in SubLayoutHeader.tsx or apply this diff

open the modal and create a new web3 wallet account, verify you see the `Welcome to Common` modal after a new account is created.
- Verify you see the first step enabled in the welcome onboard modal
- Verify that you can save, username and email in the first step 
- Verify that you can't close the modal until you complete the first step
- Since `useWallets` logic was changed, verify that you can still create new account by the regular `<AuthModal/>`
- Now create another account, this time reload the browser and verify you see the welcome modal again after page refresh. This will show until a user adds their username (not defaulting to `Anonymous`)
