Integrate self-hosted Supabase with mem0 system

- Configure mem0 to use self-hosted Supabase instead of Qdrant for vector storage
- Update docker-compose to connect containers to localai network
- Install vecs library for Supabase pgvector integration
- Create comprehensive test suite for Supabase + mem0 integration
- Update documentation to reflect Supabase configuration
- All containers now connected to shared localai network
- Successful vector storage and retrieval tests completed
