chore(release): v1.4.30.1

Categories endpoint + conflict-resolution lock. A two-item follow-up to v1.4.30: the categorisation overlay shipped yesterday as a TypeScript map; the new `GET /api/measurement-categories` endpoint projects it over HTTP so the iOS-side picker can fetch the canonical shape rather than carry a hard-coded mirror — the unblocker the iOS team flagged as the one missing piece. In parallel the SyncMode conflict-resolution policy that the v0.6.0 standalone-first track depends on lands as §13 of `08-locked-contracts.md`.
