feat(provider): add individual test and proxy config for providers

Add support for provider-specific model test and proxy configurations:

- Add ProviderTestConfig and ProviderProxyConfig types in Rust and TypeScript
- Create ProviderAdvancedConfig component with collapsible panels
- Update stream_check service to merge provider config with global config
- Proxy config UI follows global proxy style (single URL input)

Provider-level configs stored in meta field, no database schema changes needed.
