Users landing on a repository page had no in-UI guidance on how to actually consume it — they had to know the URL scheme for each package type by hand. This adds a per-repository, per-type set of copy-pasteable Linux instructions so a repo page tells you exactly how to configure a host against it. - Add UsageInstructions component: a collapsible How do I use this? panel with monospace code boxes and copy-to-clipboard buttons, styled to match the existing detail-section/badge theme. - Generate snippets per package type (rpm, pypi, npm, docker, terraform, helm, alpine, goproxy, puppet, generic) and per class (remote proxy, local registry, virtual merged index) using the repo's real name. - Resolve the instance base URL from window.location.origin (the UI is served on the API origin) rather than hardcoding a hostname. - Render the panel on RemoteDetail, LocalDetail, and the Virtuals member expand panel.
