refactor: improve type safety and error handling in vacation management components

- Updated the `AprovarFerias.svelte` component to use specific types for `solicitacao` and `gestorId`, enhancing type safety.
- Improved error handling by refining catch blocks to handle errors more accurately.
- Made minor adjustments to ensure consistent code formatting and readability across the component.
