# Change: Update agent asset list and detail display

## Why

The current agent-side asset experience exposes too much low-value information, hides some high-value state, and requires unnecessary search-type switching. The latest requests also require shop-based filtering, clearer detail presentation, explicit pagination, and a fixed top control area so search and filters remain available while the user browses long lists.

## What Changes

- Add IoT card device-binding status to the agent asset list
- Add cascaded shop filtering for the agent IoT card and device lists
- Remove the manual search-type selector and fix search semantics by active tab
- Keep the search input and filter controls fixed at the top while the asset list scrolls underneath
- Replace bottom-reached auto pagination with an explicit load-more button for both asset tabs
- Simplify asset detail basic fields and strengthen bound-card status presentation
  - Remove `保护状态`
  - Remove `切卡模式`
  - Move the bound-card real-name status badge into the slot-title row
- Remove low-value device realtime traffic items and move "last online" into the realtime block as `最后上线时间`
- Make package effective-period text more prominent in asset detail package lists
  - Only active packages should show the effective-period line
- Adjust the current active package header content
  - Remove the order number line below the package name
  - Show the active period there as `生效期：开始时间 - 到期时间`

## Impact

  - `agent-asset-list`
  - `agent-asset-detail`
- Affected code:
  - `src/pages/agent-system/assets/index.vue`
