[MBL-982] Support Project Fragment's Flagging Property

[scottkicks]

📲 What

Adds support for the GraphQL field:

• flagging

Also adds an output signal to ProjectPageViewModel that we can use in the ProjectPageViewController when we're ready.

🤔 Why

This new property will help tell us if a user has already flagged a project. Allowing us to keep them from reporting again.

🛠 How

Added this property to the FetchProjectById & FetchProjectBySlug fragments.
Rather than add this to the base fetchproject query, we can add it only to these sub queries so that we only access this property as needed.

...
flagging {
   id
   kind
}
...

✅ Acceptance criteria

• Project page and Dashboard loads and no missing data. User can pledge/back/edit pledge/view comments/view updates, etc. No new functionality added.

[msadoon]

Approved, but check there aren't tests we can write for this new property (noted below).
