fix(ui): notifications positioning regression (#1445)

Downgrades the `vue-sonner` dependency from `2.0.0` to `1.3.0` because
the newer version relies on unocss under the hood, which can't pipe
across the web component build/boundary without modifying our css
plumbing.

The older version relied on a `styles.css` stylesheet. That stylesheet
also couldn't make it through our build pipeline, but since it was a
single asset, I vendored it via `sonner.css`.

       You or someone you depend on is using Q, the JavaScript Promise library that gave JavaScript developers strong feelings about promises. They can almost certainly migrate to the native JavaScript promise now. Thank you literally everyone for joining me in this bet against the odds. Be excellent to each other.
