refactor(domain): Row structs for from_persistence, ID newtypes, kill clippy.toml

- delete clippy.toml (too-many-arguments-threshold=20 hack)
- ChannelRow/MediaItemRow/LibraryItemRow structs for from_persistence
- SnapshotId/ActivityEventId/PlaybackRecordId newtypes
- DomainError variants use ChannelId/UserId instead of Uuid
- ActivityEvent.channel_id: Option<ChannelId> not Option<Uuid>
- InMemory repos key on newtype IDs
- AlgorithmicParams struct for schedule engine
- update all adapters/application/presentation callers
