refactor(mcp): optimize panel UI dimensions and simplify state

- Reduce max width from 4xl (896px) to 3xl (768px)
- Adjust max height from 90vh to 85vh with min-height 600px
- Remove config path display, keep only server count
- Remove McpStatus state, calculate count directly from servers
- Simplify reload function by removing redundant status updates
