## What / Why
Date & Time fields were rendering their field label as a `<span>` while
every other field type uses a proper `<label>` with a matching
`htmlFor`.
Because the element was a span it broke styles and made 'field-label'
have different styles from the rest of 'field-label's.
**Root cause:** DateTimeField failed to pass its `path` (or an explicit
`htmlFor`) to `FieldLabel`. When `FieldLabel` receives no `htmlFor`, it
intentionally downgrades to a `<span>`.
## Screenshots
### Before
*DateTime label rendered as `<span>`, causing style inconsistencies*
### After
*DateTime label now rendered as proper `<label>` element*
## Changes introduced
- `packages/ui/src/fields/DateTime/index.tsx`
- Added `path={path}` prop to `FieldLabel` component
## Behavior after the fix
- Date-time labels are now real `<label>` elements with `for="field-…"`
- Visual alignment now matches every other field type
## How to test manually
1. Run `pnpm dev fields`
2. Inspect the DateTime field markup – label is now `<label>`
3. Observe that vertical spacing matches other types of fields
