Fix podcast-only mode: skip seo_analyzer imports to prevent bs4/beautifulsoup4 loading

- Conditionally import component_logic_router only when NOT in podcast mode
- Conditionally import seo_tools_router only when NOT in podcast mode
- Both use seo_analyzer which requires beautifulsoup4
- Also added debug logging to render-build.sh to verify ALWRITY_ENABLED_FEATURES
- Added beautifulsoup4 to requirements-podcast.txt (was missing)
