Revisit in-app eligibility for iCloud sharing (#837)
Restore .sharing feature:

- Merge "Apple TV" into "iCloud" section
  - "Enabled", disabled if ineligible for .sharing
  - "Apple TV", disabled if ineligible for .appleTV || !isShared
- Footer about TV restrictions

Paywalls:

- "Share on iCloud" if ineligible for .sharing
- "Drop TV restriction" if eligible for .sharing but not for .appleTV
  - Applies to full version products (user level 2)
  - Suggest Apple TV product

Restrictions:

- Toggle CloudKit sync on remote repository based on .sharing
eligibility
- Do not start tunnel on Apple TV if ineligible for .appleTV

Fixes:

- Incorrect zip() publishers in remote repository
- Resolve duplicates in Core Data, first profile wins sorted by
lastUpdate descending
- Reload receipt on OOB IAPManager events
