chore(release): v1.4.30

Server-side prep for the next iOS TestFlight build. Five surfaces land together so the iOS engineer can pick them up in one cut-over: a locked externalId shape for daily-aggregated cumulative HealthKit rows, the SyncMode foundation columns + handshake + bulk-backfill endpoints, a first-class MoodEntry.note column that replaces the legacy tag-based workaround, a cross-source workout dedup helper, and two new MeasurementType enums plus the shared category overlay that drives the iOS permission picker and the future Insights nav.
