Till JS cf3d93fac1 test(sync): extract WriteBackup + 4 Go integration tests
Refactor: HTTP handler becomes a thin shim over a pure WriteBackup(w,
userID, createdAt, iter) function. RowIterator abstracts the store, so
tests feed synthetic ChangeRow slices and production feeds
StreamAllUserChanges. Zero behavior change in production — same bytes
on the wire.

Tests (all pass):

- TestWriteBackup_Roundtrip: three rows across two apps, assert zip has
  2 entries, events.jsonl has 3 JSON lines in order, insert omits
  fieldTimestamps, update surfaces them, manifest apps are sorted,
  eventsSha256 equals a recomputed sha of the decompressed body.
- TestWriteBackup_EmptyUser: empty userID refused up-front.
- TestWriteBackup_NoRows: zero-row export still produces a valid zip
  with an empty events.jsonl and a manifest with eventCount=0 and a
  non-empty sha (sha of empty input).
- TestWriteBackup_DefaultsSchemaVersionZeroRowsToOne: legacy rows with
  schema_version=0 clamp to 1 so the manifest never claims a protocol
  version that never existed.

Paired with the vitest zip parser suite on the TS side, this closes
the Go-writes / JS-reads round-trip without needing live mana-sync.
