/**
 * Extended block metadata for message blocks.
 *
 * @remarks
 * Extends standard block metadata with message-specific fields for
 * routing, delivery tracking, and encryption.
 *
 * Messages can use any BlockSize (Small, Medium, Large, Huge) depending on
 * the message content size. The size field from IBlockMetadata determines
 * the actual block size used for storage.
 *
 * For messages larger than a single block, isCBL will be true and cblBlockIds
 * will contain the constituent block IDs for reconstruction.
 *
 * @template TID - Platform ID type for frontend/backend DTO compatibility.
 *   Defaults to `string` for backward compatibility. Backend code can use
 *   `IMessageMetadata<GuidV4Uint8Array>` while frontend uses `IMessageMetadata<string>`.
 *
 * @see Requirements 1.3, 1.4, 1.5, 2.1, 3.5, 6.3, 10.2
