🔍 feat: Show matched model names & counts for non-exact model rules

Summary
-------
1. **Backend**
   • `model/model_meta.go`
     – Add `MatchedModels []string` and `MatchedCount int` (ignored by GORM) to expose matching details in API responses.
   • `controller/model_meta.go`
     – When processing prefix/suffix/contains rules in `fillModelExtra`, collect every matched model name, fill `MatchedModels`, and calculate `MatchedCount`.

2. **Frontend**
   • `web/src/components/table/models/ModelsColumnDefs.js`
     – Import `Tooltip`.
     – Enhance `renderNameRule` to:
       – Display tag text like “前缀 5个模型” for non-exact rules.
       – Show a tooltip listing all matched model names on hover.

Impact
------
Users now see the total number of concrete models aggregated under each prefix/suffix/contains rule and can inspect the exact list via tooltip, improving transparency in model management.
