Add the id-based reconcile tests to ReplaceProgramScheduleItemsReconcileTests:
reorder moves state with the logical item (the non-vacuous core — proven to fail
under forced-positional), insert-in-middle, delete-unreferenced, unknown-id→422,
duplicate-id→422, and stale-version+unknown-id→412 (412 precedes 422, §7c). The
GET→map→PUT lossless round-trip now round-trips r.Id so it exercises id-mode.
Threads the new int? Id through all command/wire construction sites in tests.
Docs: api-conventions §7c (stable child identity + the deliberate #2-#5 positional
asymmetry) and a decisions.md entry.

Independent Codex review of #268 found two Blockers the fork missed + two Mediums:
- Blocker: replace PUTs returned the handler's item snapshot but re-queried the root
for the ETag separately, so a racing writer could pair stale items with a newer ETag
(silent overwrite). All four controllers now reload root-then-items (version-first,
fail-safe) and 404 when the root is gone between commit and reload — matching the
Block reference. Fixes the Blocker + the Medium '200 without ETag' case together.
- Blocker: PlaylistsScreen loaded items+root via Promise.all (concurrent), pairing a
stale name with the current ETag; now sequential (items-with-meta first, then root).
- Medium: SchedulesScreen loadItems now marks not-loaded/loading up front so canEdit is
false through the 412 conflict reload (no stale-draft edits lost).
Controller unit-test mocks updated to stub the new reload query. Full suite green
(ErsatzTV.Tests 1334, web 667, check:api no drift).
