Persistence + wiring the offers screen needs, per the product decisions: - SocialSettings (keystore-backed, no plaintext): coarse area geohash + configurable relay URLs, both empty by default (no bundled public relays — don't leak metadata to third parties). Registered in DI. - createOffersCubit(): opens a SocialSession on the first configured relay when online, else a null-transport cubit that degrades gracefully. OffersCubit now closes the owning session on dispose. 4 settings tests green; offers/social suites still green.
