fix: replace raw HTML buttons with Button component in admin, remove vite-plugin-wasm

- Use Button component for photo remove, editor tab toggle, and model
  pill buttons across admin/users, admin/articles, admin/videos
- Remove vite-plugin-wasm from frontend devDependencies (no longer
  needed since WASM is served by the buttplug nginx container)
