[NT-1032] Watch Project Button Clicked Event

[ifbarrera]

📲 What

Adds the whitelisted Watch Project Button Clicked event that fires when the "Watch" button is tapped either on the discover cards or in the project page.

🤔 Why

So we can track when users tap the "Watch" button in Amplitude.

🛠 How

• adds Watch Project Button Clicked event to the datalake whitelisted events enum
• updates the naming of the tracking function, adds project properties, optionally discovery properties, and context location
• in WatchProjectViewModel, the event will be queued immediately when the user taps the button (previously we would wait for the request to succeed before tracking)

• Launch the app. Navigate to any project. Tap the "Save" icon on the navigation bar in the project page. You should see in the logs a tracking event for the data lake: Watch Project Button Clicked with the context_location property set to project_screen, and the event properties should include project properties.
