Will Miao b5a0725d2c fix(autocomplete): improve tag search ranking with popularity-based sorting ...

- Add LOG10(post_count) weighting to BM25 score for better relevance ranking
- Prioritize tag_name prefix matches above alias matches using CASE statement
- Remove frontend re-scoring logic to trust backend排序 results
- Fix pagination consistency: page N+1 scores <= page N minimum score

Key improvements:
- '1girl' (6M posts) now ranks #1 instead of #149 for search '1'
- tag_name prefix matches always appear before alias matches
- Popular tags rank higher than obscure ones with same prefix
- Consistent ordering across pagination boundaries

Test coverage:
- Add test_search_tag_name_prefix_match_priority
- Add test_search_ranks_popular_tags_higher
- Add test_search_pagination_ordering_consistency
- Add test_search_rank_score_includes_popularity_weight
- Update test data with 15 tags starting with '1'

Fixes issues with autocomplete dropdown showing inconsistent results
when scrolling through paginated search results.
