Automations tree view row menu name

In Automations (tree view), a row's ⋯ menu ends with a disabled "⌥ Name: <folder>/<name>" item. The item's label is shown and then the same text appears again as a caption under it, so the name reads twice (seen on prod, 2026-10-24, TimeSaver org). - Show the full name once: either the label or the caption, not both (`apps/web/src/lib/nameTreeRows.tsx` sets `label` and `disabledReason` to the same string). - Consider dropping the "Name:" prefix since the ⌥ icon plus the path already say what it is. Out of scope: other row-menu items, the hover card, Flat view. Done means: a tree-view automation row's ⋯ menu shows the full name exactly once; a unit test pins it.

Tree-row ⋯ full-name item now reads "Full name" with the path once on the wrapping reason line; unit test pins it. Quick gate + changed-area tests green; visual check at 1280/390 clean. PR #6823 queued in the merge lane. Memory: used mem-25288.
