Viewer/Editor role can't create SCs or BLs

[jonnalley]

When logged in as a viewer/editor, I can't create a services component or a budget line at all when creating a new contract, or trying to add an SC/BL in after a contract has already been created that I'm authorized to edit.

Expected Behavior

The SC and/or BL gets created as expected

Current Behavior

Currently, if I try to create a new SC, with or without a date, while I'm creating a new contract or not, the browser sees a 400 error. Same for a BL

Possible Cause

The Viewer/Editor role has no permissions to put, patch, or post a services component or budget line--only to get

Steps to Reproduce

1. As a basic user, Attempt to create a new contract, and when you arrive to the section in the wizard for SC, choose to create a new SC with or without any dates and choose SC1.
2. Click the button to create the SC.
3. You should get sent to the generic error page and in your developer console, you should have a 403 error

Context

saw this in dev and staging

Detailed Description

Allow Viewer/Editors to create new SCs.

Possible Implementation

Add PUT_BUDGET_LINE_ITEM, PATCH_BUDGET_LINE_ITEM, POST_BUDGET_LINE_ITEM, DELETE_BUDGET_LINE_ITEM, PUT_SERVICES_COMPONENT, PATCH_SERVICES_COMPONENT, POST_SERVICES_COMPONENT, and DELETE_SERVICES_COMPONENT to the Viewer/Editor role in all environments
