move event construction from save_review to use case, extract
infra-wiring crate (DbPool/EventBusBackend dedup), deduplicate
presentation helpers (encode_error, export streaming, multipart parsing)

MEDIUM: split LocalApContentQuery god-trait 10→3 methods, dedup movie
resolution orchestration, add RemoteActorDto/PersonDto mappers, move
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 +
ShowError rename + typed auth errors, api-types cleanup
