GIF summary per day

[mjennings061]

As a stats person, I want to know how many GIF cadets were flown each day, so that I can track out progress

Dev notes

• [x] Filter launches by Duty as "GIF"
• [x] Filter launches by unique combination of aircraft commander, second pilot, and aircraft
• [x] Calculate total number of unique GIFs flown each day
• [x] Create a table of GIFs flown each day
• [x] Create a bar chart (like MongoDB Charts) of GIFs flown this financial year
