* Fix(mobile): Add toLocal() converter for chat timestamps so requests and responses match user local time * Fix(mobile): localize chat timestamps at presentation layer, not model Keep UTC in Chat/Message models; call toLocal() only in _formatTime and _formatDateTime before reading hours/minutes. Serialize toJson with toUtc().toIso8601String() to produce unambiguous UTC strings.
