Activating #253's `Version` as an `IsConcurrencyToken` made EF guard every
UPDATE *and DELETE* of a versioned root with `WHERE Version=@orig`, so any
writer outside the If-Match contract that saves via plain `SaveChangesAsync`
throws an unhandled `DbUpdateConcurrencyException`->500 when a replace-all
editor bumps the row in its narrow load->save window (ordinary two-tab UI).

A completeness sweep (grep every `Version` bumper + every root delete, not
just the handlers PR3's close note named) found 17 exposed writers, all now
routed through `ConcurrencyExtensions.SaveChangesForcingVersion` (Phase-1
force-write: adopt the stored token and retry; rethrow only on genuine
row-deletion):
  - 9 versioned-root delete handlers (a delete has no ETag to rotate -> force
    only, no bump)
  - UpdateProgramScheduleHandler (bumps then saved plainly - the ProgramSchedule
    case PR3 only suspected; its post-commit query/enqueue also moved to
    CancellationToken.None per section 7b)
  - 7 item add/remove bumpers PR2 left on plain save:
    Add/DeleteProgramScheduleItem + Add{Items,Movie,Show,Season,Episode}ToPlaylist

Force-write (not 412) is correct: these endpoints take no If-Match, so an
unconditional delete/edit should win. No API contract change (no new response
codes) -> no OpenAPI regen.

Still deferred to #197 (cross-editor ETag rotation only, not a 500): the
non-bumping config siblings + the scanner-shared Add*ToCollection family.

Tests: RootWriterForceVersionTests races a bump *through the handler* via a
pre-tracked context (non-vacuous - reverting a handler to plain save fails the
test, verified) for the Option-delete / Either-delete / bump+update shapes,
plus the genuine-conflict rethrow branch and an explicit negative control
proving the plain-save path throws. Full ErsatzTV.Tests green (1482).

Also strips a pre-existing UTF-8 BOM from the touched handlers to satisfy the
.editorconfig `charset=utf-8` rule the pre-commit format hook enforces.

Docs: api-conventions section 7a (fan-out completeness) + decisions.md entry.

timothy 1a8c0f60de feat(playlists): wire optimistic-concurrency contract onto Playlist (#253 PR2)
Fans the frozen ETag/If-Match/412 recipe (Block reference, #253) onto the
Playlist aggregate:

- ReplacePlaylistItems command carries ExpectedVersion; the handler runs
  CheckVersion as a standalone Either after validation (so a stale write
  survives as 412, not flattened to 422 by Apply/Join), bumps Version
  unconditionally before saving, and persists via
  SaveChangesWithConcurrencyGuard (EF concurrency-token backstop).
- PlaylistViewModel carries Version; the items GET sets a strong ETag and
  the PUT parses If-Match, threads it into the command, and returns the
  refreshed ETag on success (400 on a malformed If-Match).
- Sibling item-adding handlers (AddItemsToPlaylist, AddMovie/Episode/
  Season/ShowToPlaylist) bump Version too, since they mutate the same
  editor-visible item list.
- SPA: playlists.ts exposes getPlaylistItemsWithMeta and an
  If-Match-aware updatePlaylist; PlaylistEditor holds the ETag in a ref,
  round-trips it on save, and opens a "changed elsewhere" ConfirmDialog on
  412 (mirrors BlockEditor).

Tests: new ReplacePlaylistItemsHandlerConcurrencyTests (stale/match/
force-write/no-op-bump/racing-save), new PlaylistController tests
(ETag on GET items, 400/412/thread-version/force-write on PUT), and a
vitest 412-conflict-dialog test for PlaylistsScreen. dotnet test:
1304/1304 green. web: npm run typecheck clean, npm run build clean,
vitest 664/664 green.

Ref #253 PR2.
