Add DB indexes and extract shared query methods to Database class
Add missing indexes on ratings(false_positive), drafts(source), and
draft_authors(person_id) for faster filtering. Extract 12 shared query
methods (false_positive_drafts_raw, non_false_positive_ratings_raw,
false_positive_names, rated_count, gap_count, search_gaps, search_authors,
draft_affiliation_pairs, all_persons_info, category_counts,
draft_author_count_map, source_counts) to eliminate duplicated SQL across
cli.py, data.py, and reports.py.
