🎛️ feat(web): add “Conflict Rates” filter & highlight in Model Settings Visual Editor (#1286)

Introduce the ability to quickly locate models with conflicting billing configurations.

Key points
• Added `hasConflict` flag to detect models that define both a fixed price (`ModelPrice`) and any ratio (`ModelRatio` or `CompletionRatio`).
• Added “Show Only Conflict Rates” `Checkbox` to toolbar; filtering logic now supports keyword + conflict filtering.
• Display a red `Tag` beside the model name when a conflict is detected for immediate visual feedback.
• Kept `hasConflict` state in sync during add, update and delete operations.
• Imported `Checkbox` and `Tag` from **@douyinfe/semi-ui**.
• Minor UI tweaks (circle tag style, margin) for consistency.

This enhancement helps administrators swiftly identify and resolve incompatible pricing rules, addressing the need discussed in issue #1286.
