Summary
• Backend
1. model/model_meta.go
– Added `QuotaType` field to `Model` struct (JSON only, gorm `-`).
2. model/model_groups.go
– Implemented `GetModelQuotaType(modelName)` leveraging cached pricing map.
3. controller/model_meta.go
– Enhanced `fillModelExtra` to populate `QuotaType` using new helper.
• Frontend
1. web/src/components/table/models/ModelsColumnDefs.js
– Introduced `renderQuotaType` helper that visualises billing mode with coloured tags (`teal = per-call`, `violet = per-token`).
– Added “计费类型” column (`quota_type`) to models table.
Why
Providing the billing mode alongside existing pricing/group information gives administrators instant visibility into whether each model is priced per call or per token, aligning UI with new backend metadata.
Notes
No database migration required – `quota_type` is transient, delivered via API. Frontend labels/colours can be adjusted via i18n or theme tokens if necessary.
