No input validation for compatability

[luminousleek]

Bug: Inputting an invalid compatability value does nothing - it doesn't even give an error. According to the logs, there's an assertion failure, but an exception should be thrown instead.

Steps to reproduce: Edit a person's compatability to 101, or input 101 when adding a person's compatability

The 'Original' Bug

[The team marked this bug as a duplicate of the following bug]

Add/Edit: No error message is displayed when an invalid compatibility is specified

When adding/editing a person with an invalid compatibility, the command result output does not change and no error message is shown to the user after pressing "Enter". This gives the impression that the command was successfully executed, which can cause confusion.

Steps to Reproduce:

1. Start application.
2. Run the command add n/Bob e/bob@gmail.com f/law m/Law compat/200. (Other possible inputs: -1, -400. Also reproducible with edit.)

Expected:

1. An appropriate error message is displayed to indicate that the inputted compatibility is invalid.

Actual:

1. The command result does not change and no error message is displayed. The contact list does not change.
