Configured MCP Servers: add sorting (name, server, type)

[ObnoxiousProxy]

• Motivation:
  Configured MCP servers list is hard to scan when only sorted by creation date.

• Proposed solution:
  Add sorting controls (name, associated server, type) to the Configured MCP Servers view, using client-side sort initially.

• Additional context:

  • Hooks/API: frontend/src/features/mcp/hooks/use-mcp-server-configurations.ts.
  • View: Configured MCP Servers listing under /mcp-configuration/.
