G014 Report Finalisation

[richard-jones]

• consider the "mean time to transition" label, and make sure it makes sense
• overall style review
• chart colouring for age of items charts
• chart colouring for workflow capacity chart
• Replace NVD3 legend with custom legend according to design (and align the "show as table" with them)
• No need for date range - do we need to be clear that this is a "current date" report somehow?
• Apply a retrospective date limit on the data considered (probably a year). This is needed for the capacity and the transition data, and probably the main query too
• Code cleanup
• Review the age charts and validate the data
