Run data migrations; use search title for ranking

Add an entrypoint step to execute idempotent SQL data migrations (prisma db execute) from prisma/data-migrations/*.sql so fixes that prisma db push doesn't handle are applied on startup. Add normalize-local-usernames.sql to normalize local users' plex_username and plex_id to lowercase. Update interactive search and search-indexers processor to prefer the user-provided/custom search title (searchTitle / effectiveSearchTitle) when ranking torrents and adjust debug logs to show the ranking title alongside the audiobook title/author for clearer diagnostics.
