* feat: add Ollama API key support for Turbo mode

- Add ollamaApiKey field to ProviderSettings schema
- Add ollamaApiKey to SECRET_STATE_KEYS for secure storage
- Update Ollama and NativeOllama providers to use API key for authentication
- Add UI field for Ollama API key (shown when custom base URL is provided)

This enables users to use Ollama Turbo with datacenter-grade hardware by providing an API key for authenticated Ollama instances or cloud services.

* fix: use VSCodeTextField for Ollama API key field

Remove non-existent ApiKeyField import and use standard VSCodeTextField with password type, matching other provider implementations

* Add missing translation keys for Ollama API key support

- Add providers.ollama.apiKey and providers.ollama.apiKeyHelp to all 18 language files
- Support for authenticated Ollama instances and cloud services
- Relates to PR #7425

* refactor: improve type safety for Ollama client configuration

- Replace 'any' type with proper OllamaOptions (Config) type
- Import Config type from ollama package for better type checking
