Build front-end user referral flow

[rachelhamlin]

Problem

Chat platform success is in network effects. The user referral program rewards Android users for bringing their friends and family into Status. 100 SNT to the referrer for each new user who creates an account.

App store rules prevent us from being able to offer this scheme on iOS.

Implementation

3 separate entry points for the invite flow:

• From app intro screen, in existing Invite Friends bubble
• From the + menu in chat section
• As an empty state on the Profile > Contacts screen, Start group chat flow, and Start new chat flow

Past the entry point, there are three more steps:

• https://www.figma.com/file/aS1ct66VQ6V0cio7vSqS8UoG/Chat?node-id=8738%3A597
• User invites someone out of app
• Confirmation screen displayed

Acceptance Criteria

• Please match Figma designs

Notes

Are there any steps missing from code perspective?
When is account creation by another user actually confirmed? Once user generates a key?

@errorists can you please add the designs here that inform the user of all conditions required to receive their incentive? (Incl Install Status, Buy Starterpack on Android)

[errorists]

sure, here they are
this bottom sheet is shown after any of the invite entry points are pressed

Due to license issues we'll need a flavor of the app that does not include the installreferrer library for F-Droid.

I don't know how granular this could be, but my understanding is that the app version for F-Droid would still support creating referral links, but they would only work with Play Store, and it would not need the library since F-Droid doesn't support any kind of referrals.

I assume this would be done as a separate PR from #10620.

I've opened #11029 to track this.
