test: poll Astrolabe search until the target note is indexed

The previous run on nc32 failed at the search-result assertion because
`wait_for_vector_sync` returned on the first indexed-count bump (deck
seed cards) before this specific note hit Qdrant. Replace the single
search call with a poll that retries every 2s until the unique term
returns our note, or times out after 60s with a loud diagnostic. The
previously-observed flake would now wait past the deck-card indexing
window rather than racing it.
