Refactor template management in VideoEditor to simplify template structure

Browse Source 
This commit updates the template management system in the VideoEditor by transitioning from a dictionary-based structure to a list of tuples. The new structure simplifies the handling of templates, focusing on start frames and regions without the need for template IDs or counters. Additionally, the loading and saving of templates have been streamlined, enhancing clarity and efficiency in template operations during video editing sessions.
