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.
