Feat/provider individual config (#663)
* refactor(ui): simplify UpdateBadge to minimal dot indicator * 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. * feat(ui): add failover toggle and improve proxy controls - Add FailoverToggle component with slide animation - Simplify ProxyToggle style to match FailoverToggle - Add usage statistics button when proxy is active - Fix i18n parameter passing for failover messages - Add missing failover translation keys (inQueue, addQueue, priority) - Replace AboutSection icon with app logo * fix(proxy): support system proxy fallback and provider-level proxy config - Remove no_proxy() calls in http_client.rs to allow system proxy fallback - Add get_for_provider() to build HTTP client with provider-specific proxy - Update forwarder.rs and stream_check.rs to use provider proxy config - Fix EditProviderDialog.tsx to include provider.meta in useMemo deps - Add useEffect in ProviderAdvancedConfig.tsx to sync expand state Fixes #636 Fixes #583 * fix(ui): sync toast theme with app setting * feat(settings): add log config management Fixes #612 Fixes #514 * fix(proxy): increase request body size limit to 200MB Fixes #666 * docs(proxy): update timeout config descriptions and defaults Fixes #612 * fix(proxy): filter x-goog-api-key header to prevent duplication * fix(proxy): prevent proxy recursion when system proxy points to localhost Detect if HTTP_PROXY, HTTPS_PROXY, or ALL_PROXY environment variables point to loopback addresses (localhost, 127.0.0.1), and bypass system proxy in such cases to avoid infinite request loops. * fix(i18n): add providerAdvanced i18n keys and fix failover toast parameter - Add providerAdvanced.* i18n keys to en.json, zh.json, and ja.json - Fix failover toggleFailed toast to pass detail parameter - Remove Chinese fallback text from UI for English/Japanese users * fix(tray): restore tray-provider events and enable Auto failover properly - Emit provider-switched event on tray provider click (backward compatibility) - Auto button now: starts proxy, takes over live config, enables failover * fix(log): enable dynamic log level and single file mode - Initialize log at Trace level for dynamic adjustment - Change rotation strategy to KeepSome(1) for single file - Set max file size to 1GB - Delete old log file on startup for clean start * fix(tray): fix clippy uninlined format args warning Use inline format arguments: {app_type_str} instead of {} * fix(provider): allow typing :// in endpoint URL inputs Change input type from "url" to "text" to prevent browser URL validation from blocking :// input. Closes #681 * fix(stream-check): use Gemini native streaming API format - Change endpoint from OpenAI-compatible to native streamGenerateContent - Add alt=sse parameter for SSE format response - Use x-goog-api-key header instead of Bearer token - Convert request body to Gemini contents/parts format * feat(proxy): add request logging for debugging Add debug logs for outgoing requests including URL and body content with byte size, matching the existing response logging format. * fix(log): prevent usize underflow in KeepSome rotation strategy KeepSome(n) internally computes n-2, so n=1 causes underflow. Use KeepSome(2) as the minimum safe value.
