Rethink eligibility checks (#889)

- Allow unrestricted save, but show PurchaseRequiredButton
- Warn however about paid features (FIXME)
- Redesign features in paywall
- Strip already eligible features from paywall
- List required features in restricted alert
- Localize feature descriptions
- Review propagation of paywall modifiers/reasons

Extra:

- Move more domain entities from UILibrary to CommonLibrary
- Default on-demand policy to .any (free feature)
- Fix modals not reappearing after closing with gesture
- Extend UILibrary start-up assertions
