Overzealous input check for phone numbers in add command

[randallnhr]

Problem:

1. Users are unable to add the country code such as +65 to the phone number prefix.

2. Users are not able to add 2 phone numbers for a single person.

Reason:

1. I think it might be better to allow users to use the + symbol in the phone number as there are instances where the customer's phone number is not a local number.

2. Some customer might have multiple phones that they use and might want to give both in case they are uncontactable by any one of it.

Team's Response

Thanks for your suggestion - more flexible & extensive input data checks were not a priority during previous development, but the scenarios raised here are reasonable real-world use cases. Improved phone number checks could be a valuable feature for future iterations.
