Walkthrough

This PR introduces a new "CreateCacheRatio" configuration option enabling users to control cache creation multipliers. It adds backend request handling via the controller-model layer, implements thread-safe ratio storage with JSON serialization in the ratio_setting package, and provides a frontend UI component with internationalization support across six languages.

Changes

Cohort / File(s)	Summary
Backend Controller Integration controller/option.go, model/option.go	Add "CreateCacheRatio" case to UpdateOption handler and register it in the OptionMap with routing to the ratio_setting update function.
Backend Ratio Setting Core setting/ratio_setting/cache_ratio.go	Introduce createCacheRatioMap with mutex for thread-safe storage. Add four public functions: CreateCacheRatio2JSONString (serialization), UpdateCreateCacheRatioByJSONString (deserialization with cache invalidation), GetCreateCacheRatio (single-value fetch with default 1.25), and GetCreateCacheRatioCopy (thread-safe map copy).
Backend Ratio Setting Initialization & Exposure setting/ratio_setting/model_ratio.go, setting/ratio_setting/exposed_cache.go	Initialize createCacheRatioMap in InitRatioSettings mirroring existing cacheRatioMap setup. Expose create_cache_ratio in GetExposedData() map.
Frontend State & UI Components web/src/components/settings/RatioSetting.jsx, web/src/pages/Setting/Ratio/ModelRatioSettings.jsx	Add CreateCacheRatio to initial inputs state. Introduce Form.TextArea field with JSON validation, label, guidance text, and onChange handler for user configuration.
Internationalization web/src/i18n/locales/en.json, fr.json, ja.json, ru.json, vi.json, zh.json	Add two new translation keys across all six locale files: label for "缓存创建倍率" (Cache creation ratio) and descriptive note on default behavior and 1h auto-calculation. Vietnamese locale updates existing mapping for the label.

Poem

🐰 With whiskers a\-twitch, the rabbit now sings,
A cache creation ratio—oh what it brings!
Mutex protection keeps threads in line,
JSON to JSON, a config so fine.
From five-minute gardens to one-hour glows,
The new ratio feature magically flows! ✨
