feat(api): Update API to use skill-seekers-configs repository

- Update render.yaml to clone skill-seekers-configs during build
- Update main.py to use configs_repo/official directory
- Add fallback to local configs/ for development
- Update config_analyzer to scan subdirectories recursively
- Update download endpoint to search in subdirectories
- Add configs_repository link to API root
- Add configs_repo/ to .gitignore

This separates config storage from main repo to prevent bloating.
Configs now live at: https://github.com/yusufkaraaslan/skill-seekers-configs
