Linear charts & remove duplicate days buttons

[j6ll]

Proposed Changes

• Fixes DSP issues 2899 & 2890

• Don't show the last X days button if X is equal to "whole campaign" - means we have 2 buttons that do the same thing.
• Make the line chart linear, this should more accurately represent the data than the previous curved lines

Testing Instructions

Code review should be adequate

• Find a 7-day campaign
• It should only show the "whole campaign" and not "last 7 days" button
• It can show "today/yesterday" if it is still active
• Charts should be linear
