and assets. Uses @contentful/mcp-server npm package with stdio transport.

* fix: update server definition (input type 'password' -> 'text' for CONTENTFUL_MANAGEMENT_ACCESS_TOKEN)

* fix: rename server files with transport suffix

- com.contentful-mcp.json -> com.contentful-mcp-npx.json (id: com.contentful-mcp-npx)
