refactor: replace Load More with Pagination across frontend and backend

- Replace all "Load More" / "Show More" buttons with Pagination components
  in model-list, bot-compaction, and bot-heartbeat views
- Convert backend log APIs (compaction, heartbeat, schedule) from
  cursor-based (before+limit) to offset+limit pagination with total_count
- Update SQL queries to use OFFSET+LIMIT and add COUNT queries
- Add shared parseOffsetLimit helper in handler_helpers.go
- Regenerate sqlc, Swagger docs, and TypeScript SDK
- Clean up unused i18n keys (loadMore, showMore, history.loadMore)
