F51-154 & F51-276 Order Approvals refactor

[robertsoniv]

In an effort to build our default buying experience using the minimal number of roles, remove the need for UserGroupReader and ApprovalReader when viewing orders awaiting your approval.

Summary of changes:
Functional

• Remove oc-if-roles on Order List > Awaiting My Approval tab
• Default links to All Orders so that they go straight to the Order History tab
• Remove the Order Detail > Approvals tab
  • The entire /myOrders/approvals directory has been removed
  • The UpdateOrderApproval method is now in /myOrders/orders/orders.service.js
  • The approval modal controller and template also reside in /myOrders/orders
• Remove favorite orders toggle from orders that are awaiting the current users approval
• If the order is awaiting the current users approval, display Approve & Decline buttons on the detail page
• When an order is approved or declined, return to the Order List > Awaiting My Approval tab
• Remove the ocOrderDetails service, listing buyers is not possible using shopper roles
• Add clear buttons for fromDate & toDate if they have a value
• Clear filters when switching tabs on order list
• Display a readonly input for Status on the Order List > Awaiting My Approval tab
• Hide the favorite button column on Order List > Awaiting My Approval tab

Design

• Add colored icons for each order status on the order list and detail pages
  • .success, .danger, .warning, .info is now usable on .fa icons to color them with brand colors (added to shame.less)
• Approval Modal submit button is now based on the approvers intent (Approve, Decline)
• Display order approvals beneath the order status as an unordered list
  • This should read as "Rob Watt declined on DATE" (linebreak) "COMMENTS"
