Subject: [PATCH] Improve emprestimos UX with skeleton loading and optimistic
 devolver
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Replace spinner with skeleton table rows during loading
- Apply optimistic closing for devolver dialog (instant feedback)
- Use toast.promise for background mutation with loading state
- Remove unnecessary isSubmitting state from devolver button
- Maintain table layout during filter changes (no layout shift)
