Metrics: Show contextual graphs on order & subscription pages

[birkjernstrom]

Description

Offer more contextual metrics to sellers when managing orders & subscriptions.

Current Behavior

Currently, we only show the paginated table of orders & subscriptions.

Expected Behavior

Show relevant graphs on the pages that both 1) shows the total amount & 2) paginated view amount.

E.g showing Revenue under Orders offering both:

1. Total revenue all-time across all orders
2. Revenue from the displayed orders in the paginated table

Similar for MRR on Subscriptions.
