Replace wget/SingleFile/Playwright backends with Zimit

- Zimit Docker container handles all site types (static, SPA, JS redirects)
- Removed: _detect_crawl_mode, _crawl_wget, _crawl_singlefile, preflight logic
- Added: _crawl_zimit() with Docker lifecycle management
- Simplified pipeline: submit → Zimit crawl → kiwix-manage register → done
- No more zimwriterfs step — Zimit produces ZIM directly
- Dashboard UI simplified: removed crawl mode dropdown
- Config simplified: removed reject patterns, preflight, singlefile sections
