fix: improve exception handling in status tracker

[arabcoders]

• Added support for pagination, sorting (by name, size, date, type), and searching in the file_browser endpoint. The response now includes a pagination object and supports query parameters for page, per_page, sort_by, sort_order, and search.
• Refactored StatusTracker to handle file finalization, error cleanup, and improved queue draining with better exception handling and logging.
• Improved download hooks to propagate filepath and status updates more reliably.
• Removed unnecessary call to put_terminator in download core logic.
• Documented the new file browser query parameters and response structure, including examples.
• Added and documented the new POST /api/history/{id}/nfo endpoint for generating NFO metadata files for completed downloads, including error cases and supported modes.
