The UTable component was not reliably updating when items were added, edited, or removed due to a reactivity issue. This commit resolves the problem by forcing the table to re-render when its data source
changes.
- A `watch` with `{ deep: true }` is now used to monitor the `items` array for any changes.
- A `tableKey` is incremented on each change and passed as a `:key` to `UTable`, triggering a re-mount.
Additionally, data handling has been made more robust:
- The localStorage serializer now gracefully handles parsing errors and ensures data integrity for dates and tags.
- Added null-safe access for tags in the table template to prevent rendering errors.
