ui-manchette: duplicate keys for PathLayer

[emersion]

usePaths() uses path.departure_time as id, however there is no guarantee that these are unique.

Warning: Encountered two children with the same key, `2024-06-04T08:30:00Z`. Keys should be unique so that components maintain their identity across updates. Non-unique keys may cause children to be duplicated and/or omitted — the behavior is unsupported and could change in a future version.
