feat(web): show Patreon supporters on the web build too

The browser can't call the Patreon API directly (CORS, and the token
would be exposed in the bundle), so the web build fetches a
pre-generated supporters.json served on the same origin. The Pages
workflow generates it server-side with the token (CI secret) after the
trunk build. Native keeps its live API fetch.

serde_json moves to the shared dependencies so the wasm build can parse
the list.
