chore(release): v1.32.24 — isolate Polar collections and log envelope drift

Per-collection isolation for the Polar vitals sync: one unavailable data type
no longer blanks the rest, a failing collection is named on the integration
status, and an unexpected response shape is logged instead of reading as no
data. Bump version, regenerate the OpenAPI version string, add the changelog
entry.
