Refactor mock reporting data and class methods

All mock reporting data was moved to a JSON file. The concept of
what JEDI CLIN a particular environment drew money from was added to the
data.

This change had a cascade effect to the reporting class methods,
templates, and Vue components that ingested that reporting data. Many of
these files were modified to adapt to these changes. This also included
modifying the obligated funding bar graphs to reflect new design
changes.
