Better phone number filtering for twillio and SMS in integrations page

[cheeseblubber]

Problem Right now if you enter a phone number without the area code or have the wrong formatting in phone number section it will fail silently and not work. We should make sure that there is a country code and that it can work regardless of the text formatting

Solution It should validate that it has a country code and we shouldn't care about formatting

@a8t you might have some context on this

Twilio has a free phone number validator service that we already use for something else. Maybe we can also pair with a client-side validation. (is a phone number regex stupid?)

Yeah I think just some client side validation + string formatting would be ideal. It doesn't work if we add spaces in to the phone number
