Fathom events - 18.1

[0xVenky]

• Trigger an event everytime user clicks Pro
• Trigger an event everytime user clicks Off
• Differentiate volume from market orders and limit orders for CoW
• Time spent on Pro mode? How many users spend more than 15 seconds, so everytime we refresh trade history, send an event with a counter.
• How many times user updates Limit order price? And at what % above or below user places the limit order?

Just summarizing:

We add a new type event type similar to ecoRouter volume metric, but named proMode, and then compare the volumes.
