Add next payment due dates fields for Fixed Budget projects

[mohitsharma-22]

Describe the problem For fixed budget projects, the payment terms and dates for invoices are decided at the beginning of the project. The billing dates may vary from project to project and it may not be monthly. Because we don't have a proper place to track these dates, sometimes these are missed resulting in not sending the invoices timely and unnecessary confusion.

Expected behavior

• [ ] In the project screen, there needs to be a repeatable field that will capture the invoice dates for a fixed billing project.
• [ ] The repeatable field will consist of the following fields: percentage and invoice date. The repeatable field should be called "Project Payment Terms". This will be same as project team member functionality.
• [ ] The user can create multiple instances of repeatable fields (like add project team member functionality).
• [ ] The total percentage of all the payment terms should be exact 100%. This validation should work when user saves these fields.
• [ ] The invoice dates against all payment percentages should be required field.
• [ ] On save, the page should reload and the system should show all the saved payment terms

Adding a screenshot for the place where we need fields to add the payment schedule. We also need to see these details are the project details page, once saved.

As per discussion Mohit

1. For fixed budget projects we get payments in phases (like first payment after requirements documentation, second payment after design completion, third payment after 60% development is complete etc etc)

2. So we need payment's due date fields along with the description of the payment.

3. So we can have multiple due date fields(type-Date) along with payment Description(Type-Text) field on the project details page.

4. All the due dates to be displayed along with their description on the project details show page.
