Enhance ChannelDebugCollector and LibraryDebugCollector for improved data handling

Refactored the ChannelDebugCollector to introduce a new RunScope record, consolidating channel, template, and time horizon data for better readability and maintainability. Updated methods to utilize the new RunScope structure, enhancing the clarity of debug file generation. In the LibraryDebugCollector, added AsSplitQuery to optimize database queries and improve performance. Cleaned up unused parameters and ensured consistent handling of asset statuses. These changes aim to streamline debug data collection and improve overall efficiency.
