feat: Sprint 4 — indexed search + job rate limiting

Search:
- New PageSearchIndex model (page_search table)
- New search/indexer.py service with index_page(), search_pages(), reindex_all()
- Refactored /search endpoint to query DB instead of filesystem scan
- Added POST /search/reindex endpoint for full rebuild
- Search index populated on pipeline completion (job_runner) and corrections (pages)
- 21 new search index unit tests + 15 updated API search tests

Rate limiting:
- Guard against duplicate pipeline runs on /corpora/{id}/run and /pages/{id}/run
- Returns HTTP 409 if active jobs (pending/claimed/running) already exist
- 4 new guard tests
