refactor: fix all clippy warnings properly

- UserProfile struct groups display_name/bio/avatar/banner/also_known_as/profile_fields
- User::from_persistence takes UserProfile (6 args, was 11)
- PersistedReview struct for Review::from_persistence (1 arg, was 8)
- WatchlistApInput struct for watchlist_to_ap_object (1 arg, was 8)
- ActivityPubDeps struct for activitypub::wire (1 arg, was 11)
- FederationRepos type alias for wire() return types
- FeedSortBy: impl std::str::FromStr instead of inherent from_str
- postgres users.rs: row_to_user takes &PgRow like sqlite
- collapse nested ifs in multipart handlers
- type alias for complex return types (image-converter, worker)
- tui: allow large_enum_variant at crate level (pre-existing, unrelated)
