example(document): replace mocket with moonback

[bobzhang]

oboard/mocket was the last mocket user in the repo, and it no longer builds: @async/http moved to CaseInsensitiveString headers, so mocket.native.mbt fails to check.

mocket.native.mbt:370  has type : Map[String, String]
                       wanted   : Map[@async/http.CaseInsensitiveString, String]

hackwaly/moonback is already the server library behind rabbita/server, so the example now goes through that rather than carrying a second HTTP stack.

Layout

moonback is native+wasm only, so the single main package (which used #cfg(target=...) to be both the browser entry and the server) had to split into the layout warren already expects:

app/	the shared component, js+native+wasm
main/	browser entry, hydrates the server-rendered document
cmd/server/	server entry, native+wasm

cmd/server registers /issues as a @moonback.Module and hands it to @rabbita_server.Server, which supplies the page route and the static middleware. That replaces the hand-rolled /assets/index.js and /assets/styles.css handlers, so the server entry is ~25 lines. Assets move to /index.js and /styles.css to match the head page_service injects, and the component no longer writes its own <script> tag.

This is the first in-repo consumer of rabbita/server.

Verification

Checked on js, native, and wasm — and actually run, not just checked:

/           200  full SSR document: data-theme, <title>5</title>, and a
                 __rabbita_transcript already carrying the /issues payload
/issues     200  application/json
/index.js   200  text/javascript; charset=utf-8  (249363 bytes)
/styles.css 200  text/css; charset=utf-8

The transcript is the interesting one: create_resource resolves /issues during SSR, so the list is in the response document instead of being refetched after hydration.

warren dev --browser-entry main --server-target native also works — warren picks up cmd/server as the server entry and injects the live-reload client through WARREN_CLIENT.

The example's rabbita dependency was pinned at 0.12.2; bumped to 0.15.5 to match the repo.
