Adds the shared optimistic-concurrency contract so a stale second tab can no longer
silently overwrite a fresher edit. PR1 lands the infra + the Block reference aggregate;
PRs 2–4 fan the same recipe across the other 8 roots (design: #253#issuecomment-8472).

Contract
- `IVersionedAggregate` (`int Version`) on all 9 replace-all roots (ProgramSchedule,
  Block, Template, DecoTemplate, Playlist, Collection, Playout, MultiCollection,
  RerunCollection), EF-mapped `.IsConcurrencyToken()`; one dual-provider migration
  `AddAggregateVersions` (nullable:false, default 0).
- Strong `ETag` of `Version` on the aggregate GET; `If-Match` on the PUT; mismatch →
  412 (distinct from the §3a 409 build-lock guard). Successful PUT returns the new ETag.
- `PreconditionFailedError : BaseError` → 412 in `ApiResults.ToErrorResult`;
  `ConcurrencyHeaders.ParseIfMatch/SetETag`; malformed If-Match → 400; `*`/absent =
  Phase-1 force-write.

Block reference wiring
- Handler: standalone `Either` via `CheckVersion` AFTER validation (never through
  `Apply`, which Join()-flattens the subtype to 422), unconditional `Version++`,
  `SaveChangesWithConcurrencyGuard` backstop (DbUpdateConcurrencyException → 412).
- `BlockViewModel.Version` (header-only, not echoed in the body); controller sets the
  ETag on GET items and on the successful PUT.
- SPA: `client.requestWithMeta` seam; `blocks.getBlockItemsWithMeta` + `replaceBlock`
  If-Match/ETag round-trip; `BlockEditor` holds the ETag, sends If-Match, and on 412
  opens a blocking "changed elsewhere — reload" dialog.

Tests
- Handler contract tests: stale-If-Match → 412 (no mutation), matching/absent → success
  + bump, no-op save still bumps, and a two-context racing save → 412; proven
  non-vacuous (drop `.IsConcurrencyToken()` → the race test fails).
- Controller tests: malformed If-Match → 400, If-Match threaded to the command, ETag on
  GET/PUT, 412 passthrough. SPA: requestWithMeta ETag, replaceBlock If-Match, 412 dialog.

Docs: api-conventions §7a, spa-conventions §4a, domain-model glossary, decisions log.

timothyandClaude Fable 5 a0521cd6dc feat(web): Templates screen (list + editor) on the REST API
Adds a ChicoryTV Templates screen under /app/templates: grouped template
list with group/template create, copy, and delete, and a
/app/templates/{id} editor (name, add-content row that picks a block
group -> block -> five-minute start time, a time-sorted item table with
remove, and a client-side overlap warning that mirrors
ReplaceTemplateItemsHandler's server-side check before allowing save).

Deviates from the Blazor TemplateEditor.razor's drag-to-place day
calendar: uses a plain sorted table + picker row instead, per the S2
spec (parity, not a pixel port).

Adds web/src/api/templates.ts client + copyBlock to blocks.ts (S1 left
the block-copy endpoint unwired; CopyBlock's CQRS shape is identical to
CopyTemplate so it rides along here), plus regenerated v1.d.ts types.

timothyandClaude Fable 5 ecd9d526d0 feat(web): Blocks screen (list + editor) on the REST API
Adds a ChicoryTV Blocks screen under /app/blocks: grouped block list with
group/block create + delete, and a /app/blocks/{id} editor (name, duration
hours + 5-min increments, stop-scheduling, item table with add/remove/move/
duplicate, per-item collection-type pickers via debounced search endpoints,
conditional playback-order, EPG/watermark toggles, watermark & graphics
multi-selects, and a non-persisting playout preview dialog).

Adds web/src/api/blocks.ts client + regenerated v1.d.ts types.
