refactor: remaining MEDIUM — CQRS splits, DI Deps, profile dedup, event Value, response enum

M1: MovieRepository→MovieCommand/MovieQuery, WatchEventRepository→
WatchEventCommand/WatchEventQuery
M2: goals/ and import/ use Deps structs
M7: extract upload_image helper in update_profile
M8: FederationDeliveryRequested activity_json String→serde_json::Value
M11: UserProfileResponse uses ProfileViewData enum
