New bookmarks feature: domain model, repository, service and handler supporting list/create/update/delete. Public endpoint exposes the admin user's bookmarks for the homepage navigation grid; authenticated endpoints scope by user. Dev Dockerfile drops air for plain `go run` and uses goproxy.cn to avoid build failures on the deploy host. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
