Integrate ScraperManager into BibleManager for production use

- BibleManager now uses ScraperManager instead of direct BibleScraper
- Provides rate limiting, source fallback, and deduplication automatically
- All 213 tests passing ✅

Benefits in production:
- Automatic rate limiting (1s min delay per domain) prevents server bans
- Automatic fallback to BibleHub when BibleGateway fails
- Automatic request deduplication prevents duplicate concurrent fetches
- Better error handling with exponential backoff
