ui/order-draft: silence hydrate path on non-UUID game ids + Phase 10 e2e fixture upgrade

Phase 14's auto-sync calls `uuidToHiLo` on every layout boot. The
existing Phase 10 e2e specs use a placeholder string `test-shell`
as the game id, which throws in the FBS request encoder and
surfaced as a noisy `console.warn` plus a flaky webkit-desktop
test on the local-ci ARM runner.

`OrderDraftStore.hydrateFromServer` and `scheduleSync` now skip
when the active game id isn't a real UUID — the auto-sync path is
inert for fixture data and the placeholder-warning is gone. The
Phase 10 spec switches to a deterministic UUID
(`10101010-1010-1010-1010-101010101010`) so future Phase 14+
specs don't have to special-case it.
