## Why
The alpine local repo (a real apk repo with auto-generated per-arch APKINDEX) and the new github_alpine remote (metadata-only apk index synthesized from a GitHub repo's release .apk assets) shipped without any "How do I use this?" UI guidance, unlike deb/github_deb. This adds the matching client instructions so users can consume and publish to these repos.
## How
- Extend `case 'alpine':` in `UsageInstructions.tsx` to branch on `isLocal` (mirroring rpm/deb):
- LOCAL: "Add the apk repo" snippet appends `${url}/api/v1/local/<name>` to `/etc/apk/repositories` with `apk update/add --allow-untrusted` (served unsigned, parity with rpm gpgcheck=0), plus a "Publish a .apk" snippet uploading to the canonical `<arch>/<name>-<version>.apk` path (APKINDEX carries no filename, so path must match or install 404s).
- REMOTE: existing caching-proxy snippet kept unchanged.
- Add `case 'github_alpine':` (always remote-class): "Add the apk repo (metadata-only, from GitHub releases)" snippet with `--allow-untrusted`; note explains the per-arch APKINDEX is synthesized from release .apk assets and downloads redirect to the backing releases remote.
- No other cases touched. `npm run build` (tsc typecheck + vite) passes; pre-commit passes.

## Why
The `deb` and `github_deb` repository types had no tailored "How do I use this?" snippets in the UI — they fell through to the generic default (curl-a-file-by-path), which does not tell a user how to actually wire the repo into apt. This adds real, end-to-end-validated apt instructions mirroring how the existing package types (rpm, npm, etc.) are handled.
## How
- Adds a `case 'deb':` to `buildSnippets` that branches on `isLocal`: a flat real apt repo served at `/api/v1/local/<name>/ ./` with `[trusted=yes]` plus a publish-a-.deb snippet for locals, and a caching-proxy `deb <proxy> <suite> <component>` form (upstream-signed, no `[trusted=yes]`) for remotes.
- Adds a `case 'github_deb':` emitting the metadata-only flat form `deb [trusted=yes] <proxy>/ ./`, whose index is synthesized from a GitHub repo's release .deb assets.
- Reuses the existing `url`/`proxy`/`isLocal` helpers and matches the surrounding case style; leaves the rpm and other cases untouched.

## Why
A repository detail page in the ArtifactAPI UI showed configuration and stats, but nothing that told a user how to actually *consume* the repo. You had to already know the per-package-type URL scheme (yum baseurl, pip index-url, docker registry host, terraform source address, ...) by hand. This adds an in-page, copy-pasteable "How do I use this?" panel so each repo page tells you exactly how to point a Linux host at it.
## Changes
- Add a `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 instructions per package type (rpm, pypi, npm, docker, terraform, helm, alpine, goproxy, puppet, generic) and per class:
- **remote** — consume via the caching proxy (`/api/v1/remote/<name>/...`).
- **local** — consume via the real registry endpoint, plus a publish/push example (rpm `PUT .../files/`, docker Registry V2 push, terraform provider upload).
- **virtual** — consume the merged index via `/api/v1/virtual/<name>/...` using the same per-type client config.
- Interpolate the repository's real name into every snippet so it is genuinely copy-pasteable.
- Resolve the instance base URL from `window.location.origin` (the UI is served on the API origin, client `BASE=''`) instead of hardcoding a hostname; falls back to the public host only when `window` is unavailable.
- Render the panel on `RemoteDetail`, `LocalDetail`, and the `Virtuals` member-expand panel.
## Verification
- `npm run build` (tsc typecheck + vite build) passes.
- Rendered the component in headless Chromium against real repo data for rpm remote, rpm local (with publish), docker local (with push), terraform local (HCL `required_providers` + signing note), and a pypi virtual — all snippets render with the correct URLs and theme.
