USER STORY: Validation on Type field

[MoniPar]

As a developer, I can write validation for the type field so that users are only allowed to choose the type in the right order.

Acceptance Criteria

1. Users get a validation error if they choose an appointment type in the wrong order.
2. First appointment is always consultation, if user has already scheduled a consultation then they can only choose details & design, so on so forth.

Tasks

• Create a function to get the user's appointments.
• Add conditionals to allow users to select specific types depending on what is in their appointment's list.
• Might need to research this further as not sure it will be possible with the way I have written the constants.
