Slice C of the async-op contract normalization:
- channel reset (POST /api/channels/{channelNumber}/playout/reset) now
returns 202 Accepted (was 200 Ok) — it only queues a background rebuild
- reset-all (POST /api/playouts/reset-all) still 202 but now returns a
ResetAllPlayoutsResponseModel body reporting QueuedPlayoutIds /
SkippedLocked / SkippedUnsupported instead of silently swallowing skips;
handler returns a new ResetAllPlayoutsResult record
- single-playout GET (GET /api/playouts/{id}) now exposes IsLocked on
PlayoutResponseModel, set from IEntityLocker.IsPlayoutLocked mirroring
the list projection — gives a polling client the lock flag
Tests: channel reset asserts 202; reset-all asserts 202 + skipped-body
shape; single GET asserts IsLocked; new ResetAllPlayoutsHandlerTests
(in-memory SQLite) asserts locked/ExternalJson/None land in skipped lists
and eligible playouts in queued. docs/api-conventions.md §3a updated.
