[ABW-1112] iCloud profile sync

[CyonAlexRDX]

Jira ticket -> https://radixdlt.atlassian.net/browse/ABW-1112

What was done

• Update the Profile with the Header model, containing all of the metadata about the profile.
• Along with being stored in Profile, the Header for each Profile is also stored in a separate HeaderList entity, to facilitate Profile cloud backup.
• Implemented the necessary screens to allow users to restore from a backup.
• Implemented the logic for Profile ownership, when a Profile shared across multiple devices can be owned only by one device.

Excellent. Just some micro comments

Will do an additional round of testing, after that will merge it.

@CyonAlexRDX , @GhenadieVP @kugel3 I am going to update the snapshot on Android too. I have a question related to the new header:

Are we going to keep the creationDate and lastModified dates along with the ones stored inside creatingDevice.date & lastUsedOnDevice.date?

We can remove the stored property creationDate from header actually, and in code let
it be a computed property which reads out date from creatingDevice. creatingDevice itself is immutable in the struct, thus its date is immutable.

lastUsedOnDevice is mutable and set when a phone claims the profile, and that date is not the same as profiles lastModified date, which is the date when any change to profile occurred

Ok understood Alex thanks! So lastUsedOnDevice.date is the instant when the device claimed the profile and lastModified is when the user modifies the profile.
