Fix Image src in dev mode

Parent: #731

Whenever I run vite in dev mode it complains that we haven’t given Image a src. We want it to fallback to the placeholder, and this works in production, but in dev it throws an error.

gonna pause this for now to focus on tauri and will just run tauri with a production build always, otherwise i’ll be tracking down whether or not issues are due to tauri or running in dev mode
