Detailed changes
Backend
• `controller/pricing.go` now includes `auto_groups` in `/api/pricing` response, sourced from `setting.AutoGroups`.
Frontend
• `useModelPricingData.js`
– Parses `auto_groups` and exposes `autoGroups` state.
• `PricingPage.jsx` → `ModelDetailSideSheet.jsx` → `ModelPricingTable.jsx`
– Thread `autoGroups` through component tree.
• `ModelPricingTable.jsx`
– Removes deprecated `getGroupDescription` / `Tooltip`.
– Filters out `auto` when building price table rows.
– Renders a descriptive banner: “auto 分组调用链路 → auto → group1 → …”, clarifying fallback order without showing prices.
• Minor i18n tweak: adds `auto分组调用链路` key for the banner text.
Why
Users were confused by the “auto” tag appearing alongside regular groups with no price.
This change:
1. Makes the routing chain explicit.
2. Keeps the pricing table focused on billable groups.
No breaking API changes; existing clients can ignore the new `auto_groups` field.
