Several entrées for the same client often share the same title
format ("EPAU - 2026-01-05"), which isn't enough to tell them apart
when linking a sortie. Append the amount and the notes/invoice
reference to each suggestion's label -- verified end to end (real
autocomplete HTTP request, then an actual save) that the richer label
still parses back to the right node id.
