fix: silence useImage onError rethrow at every call site

VueUse `useImage` (built on `useAsyncState`) defaults its `onError` to
`globalThis.reportError`. When an `<img>` fires `onerror`, the Promise
rejects with a raw DOM Event and `reportError` dispatches it to
`window`, which Datadog RUM's browser integration logs as an uncaught
error. This has been the top RUM issue on prod-v2 for 30+ days
(~192k events / 3,270 sessions per day).

Pass `onError: () => {}` to every `useImage` call site — the consumers
already surface error state via the returned `error` ref and handle it
in-template, so the rethrow is pure noise.

Fixes FE-224
