fix: add manutic/nomic-embed-code model for Ollama compatibility

- Add manutic/nomic-embed-code to Ollama and OpenAI Compatible embedding model profiles
- Provides same configuration as nomic-embed-code (3584 dimensions, 0.15 score threshold, code search query prefix)
- Resolves issue where users cannot use nomic-embed-code with Ollama since only community version exists
- Enables flexible embedding model selection for code indexing with Ollama

Fixes #5687
