Wolfgang 26f5a7370c feat: External workflow file support with dynamic credential replacement
- Add --workflow-file option to install.sh (default: RAGKI-BotPGVector.json)
- Add --ollama-model option (default: ministral-3:3b)
- Add --embedding-model option (default: nomic-embed-text:latest)
- Update libsupabase.sh to read workflow from external JSON file
- Add Python script for dynamic credential ID replacement in workflow
- Remove id, versionId, meta, tags, active, pinData from imported workflow
- Include RAGKI-BotPGVector.json as default workflow template

Tested successfully on container sb-1769180683
