WIP: New Forecasting Dashboard

[koolgax99]

Description

Currently, the forecasting dashboard does not start due to various reasons like package degradation issues, changes in the data format etc.

Recently, the data processing and downloading format has been changed and it is not supported by the previously built dashboard. The major update from the previously built dashboards is the change in the data retrieval functions in the plots.

In this PR I have rejuvenated the old Forecasting Dashboard by refactoring codes for the plots and making it more dynamic.
