Update taxonomy.json to expand categories and improve evidence handling. Introduce new categories for 'NTR', 'incest', 'nakadashi', and 'monster_girl', along with updated aliases and ignore lists. Adjust priorities for existing categories and enhance tests in test_taxonomy.py to validate new folder routes and evidence logic.

Refactor tagging logic in backend API and services. Replace choose_best_tags with choose_best_destination for improved tag selection. Integrate taxonomy resolution for folder names in save_settings and discover_tag_folders functions, enhancing tag mapping accuracy. Update relevant imports and ensure consistency in tag handling.
