/// SYNCHRONIZATION STRATEGY:
/// - Uses delta API for both initial and incremental sync
/// - Initial sync: Downloads last 30 days of emails with metadata only
/// - Initial sync: Downloads messages using the account's configured cutoff date with metadata only
/// - Incremental sync: Uses delta token to get only changes since last sync
/// - Messages are downloaded with metadata only (no MIME content during sync)
/// - MIME files are downloaded on-demand when user explicitly reads a message
///
/// Key implementation details:
/// - SynchronizeFolderAsync: Main entry point for per-folder synchronization
/// - DownloadMailsForInitialSyncAsync: Downloads last 30 days using delta API with filter
/// - DownloadMailsForInitialSyncAsync: Downloads messages using delta API with an optional cutoff filter
/// - ProcessDeltaChangesAsync: Processes incremental changes using delta token
/// - DownloadMessageMetadataBatchAsync: Downloads metadata in batches using Graph batch API
/// - CreateMailCopyFromMessageAsync: Creates MailCopy from Message metadata
