refactor(ollamaManager): simplify status messages for model updates

The commit simplifies the status messages displayed when updating Ollama models by:
- Removing conditional message logic based on hostname selection
- Standardising the success message to always use "updated to"
- Simplifying the error message to consistently use "updating" terminology
- Removing unnecessary variables that were used for message construction
