[#30] Return the draft id from /sync so re-saved drafts update in place

A locally created draft only learned its backend id through the manual
Sync Datapoint round-trip. Until then every re-save uploaded with no
?id=, and the uuid fallback cannot match child forms (a monitoring
draft carries its parent's uuid) — so each edit-then-autosync cycle
created another backend draft row.

- /device/sync now responds {message, id} on create, update and replay
  alike (the replay early-return exposes the original row's id, which
  also lets a device recover a draftId lost to a dropped response)
- The app stores the returned id as draftId in markSynced for draft
  rows only — a draftId on a submitted row would flip its sync URL to
  the is_published variant
- submission_key stays: it dedupes replays of a single attempt (lost
  response, concurrent retries), while draftId identifies the row
  across deliberate saves — neither subsumes the other

Covered by two new tests; full v1_data + v1_mobile suite passes (481).
