fix(cli): filter blocked MCP servers case-insensitively to prevent duplication

Fixes a bug where disconnected MCP servers were listed twice in '/mcp list' (once as 'Disconnected' and once as 'Blocked') due to a strict string equality check that failed when extension server names had different casing or trailing whitespace compared to user configuration. Updated the filter in 'McpStatus.tsx' to use '.trim().toLowerCase()'.
