Updates: Model Management (#8248)

## Summary

Model management improvements: refactored tag API, enhanced UX for
trigger phrases and editing.

## Changes

### API Refactor
- Add `addAssetTags` (POST) and `removeAssetTags` (DELETE) endpoints in
assetService
- `updateAssetTags` now computes diff and calls remove/add serially
- Add `TagsOperationResult` schema; cache syncs with server response

### UX Improvements
- **Trigger phrases**: click to copy individual phrases, copy-all button
in header
- **Display name**: show edit icon on hover instead of relying on
double-click
- **Model type**: show plain text when immutable instead of disabled
select
- **Tags input**: only show edit icon on hover
- **Field labels**: updated styling to use muted foreground color
- **Optimistic update** for model type selection
