New colouring scheme & "fixed" y-axis scales for load plots

### Changes to genomics-dashboard page
* New colouring scheme to indicate time in production for separate projects based on defined time limits in load plots
* "Fixed" y-axis scales for load plots. If data exceeds the scale, it will be changed to a multiple of the default max to fit the data. Scale numbering will change colour to indicate the scale change
* Corrected the delivery time calculation to use aborted samples to find start dates
* Number of worksets not calculated for projects in the ongoing panel

### Changes to goals page
* Made plot bigger
* Clarified application types in title

\+ the usual insertion of commented-out code :)
