Third dev pre-release of the 1.2.0 minor. Data-safety upgrade to how diary items and water round-trip between clients and the server.

Fixed

• Diary items and water are now merged per-entry across devices instead of replaced wholesale. Every diary item and water log carries a stable identifier, and deletions travel as explicit tombstones. If a client’s local copy of a day is stale, its next write can no longer overwrite items or water that the server holds; the merge preserves anything the client didn’t address. Existing rows get identifiers assigned automatically on the first server start after upgrade. No user-visible change under normal use; the safety kicks in when two devices race, when a mobile local cache thins out, or when an offline delete is synced later.
