New Profile creation/editing better field validation/error handling

[prury]

When creating a new profile/editing using the new profile design, user have to type the full address with https:// in order for it to work

Web Link

• When field has lost focus, add https:// to the url if it isn't already present

---

• Prevent the full address from being shown on

Farcaster

if i type /koda on the farcaster field, it will redirect me to https://warpcast.com//koda instead of https://warpcast.com/koda, so we may have to add the / there as well for the user.

• Make sure the correct handle is sent to worker, whether or not the user has chosen to start with /
