Give FTA and Field Supervisor access to Cycle Time Report on FTC Cloud

**Is your feature request related to a problem? Please describe.**
As an FTA/FS, I like to learn from how my events perform and figure out how to plan for future events. A big part of this is cycle times, in combination with other notes I take. I found out Head Referees have access to the cycle time report already, so it should naturally extend to FTA/FS

**Describe the solution you'd like**
When assigned as an FTA or FS for an event, that event shows up in FTC Cloud such that I can access the cycle time report

**Describe alternatives you've considered**
1. Remember to download the report and/or the event DB before I leave the event
2. Get Event Admin access to all my events

**Additional context**
Somewhat related to #939

Start by tracing how FTC Cloud assigns event roles and how existing Head Referee access to the cycle time report is granted. Done means an FTA or Field Supervisor assigned to an event can access that event's cycle time report without Event Admin access.
