Forward looking - requires changes

[amy-silcock]

With the inclusion of @budget-not provided attribute as part of the 2.03 upgrade process, changes are required to the current methodology for forward-looking.

If budget-not-provided is present, the Dashboard logic should be that all required budgets exist.

As a result, the pseudocode on the Forward-looking page should change:
FROM:

To calculate the "Current activities with budgets" column, count the number of activities that are:
at a relevant hierarchical level (see above)
AND current
AND contain at least one budget budget with a budget year (as described above) that matches the year of the column

TO:
