AppConfig to infra-wiring, fix SocialQueryPort Uuid→UserId, replace
stringly-typed api-types with domain enums, move count_reviews_in_year
to StatsRepository, dedup event publisher cfg blocks, extract
should_enrich, move group_by_month to application, dedup
count_local_posts, add FederationFlags Default, TUI input helper +
