Models: - Convert Conversation and ChatMessage to SwiftData @Model classes with a one-to-many relationship and cascade delete. - Rename ChatMessage.id to clientID and drop Conversation.id in favor of jid (the string id would clash with PersistentIdentifier). - Keep MessageReaction as a Codable value stored in an array attribute. Persistence: - Add ArchiveStore, a per-account ModelContainer/ModelContext that replaces the JSON ChatArchive with load/save/erase. - Add ArchiveMetadataRecord for the durable MAM checkpoints, cursor, locally deleted message IDs and roster contact JIDs. - Add LegacyArchiveImporter to import the old JSON snapshot once and delete the file afterwards, preserving existing history. AppModel: - Replace ChatArchive with ArchiveStore and persist via context.save(); insert new models and delete the replaced object on upsert merges so SwiftData never keeps an orphaned duplicate. Tests: - Replace ChatArchiveTests with ArchiveStoreTests (store round-trip and legacy import) and drop the now-obsolete Codable round-trip assertions.
