Summary
• Swapped out the old availability UI for clearer icon-based feedback.
• Users now see a green check icon when their group can use a model and a red × icon (with tooltip) when it cannot.

Details
1. Imports
   • Removed deprecated `IconVerify`.
   • Added `IconCheckCircleStroked` ✅ and `IconClose` ❌ for new states.

2. Availability column
   • `renderAvailable` now
     – Shows a green `IconCheckCircleStroked` inside a popover (“Your group can use this model”).
     – Shows a red `IconClose` inside a popover (“你的分组无权使用该模型”) when the model is inaccessible.
     – Eliminates the empty cell/grey tag fallback.

3. Group tag
   • Updated selected-group tag to use `IconCheckCircleStroked` for visual consistency.

Result
Improves UX by providing explicit visual cues for model availability and removes ambiguous blank cells.
