documents.spec.ts: replace getByText with getByRole('heading') to avoid
Svelte's #svelte-announcer matching the same text (strict mode violation).
SaveBar.svelte: move <form id="mark-for-review-form"> out of the component
and into +page.svelte as a sibling of delete-form. The form was previously
nested inside <form id="update-form">, which is invalid HTML. The browser
auto-repaired it, causing a Svelte hydration mismatch that broke the edit
form's use:enhance, preventing version snapshots from being recorded —
leaving history tests with 0 versions instead of the expected 2.
