fix: separate Naver blog/web auto-search dedup; drop dead helpers

_auto_naver_search previously used a shared 'continue' so a duplicate blog
query skipped that iteration's web search entirely. Split into independent
per-signature guards so blog and web auto-searches dedup separately.

Also remove unused private helpers left by the god-file split:
_is_generic_data_image_attr, _search_result_page_image_urls, _count,
_set_active_queue (all grep-verified to have no callers).
