feat(item): add delete functionality

This commit introduces the ability to delete items. A new `ItemDeleteModal` component provides a confirmation step
before removal.

- Adds a 'Delete' option to the action menu in the items table.
- Refactors the `useItems` composable to ensure reactivity with `useLocalStorage` by creating new array references on
add/remove operations.
- Renames `AddModal` to `EditModal` to better align with its future role in both adding and editing items.
