Clears the still-live findings from #172 (verified against main; #2/#4/#7 and the
auth/search/Trakt tail were already deliberate-documented or fixed since 2026-07-07).
- Null/empty Name → 500 (10 create/replace handlers). Block/Template/DecoTemplate/Deco
Create+Replace/Update + UpdateFFmpegProfile did `request.Name.Length > 50` on a
client-nullable string → unhandled NullReferenceException → HTTP 500 (no global
exception filter). Now `string.IsNullOrWhiteSpace(request.Name) || .Length > 50` →
422; also rejects empty/whitespace names, matching the group-create handlers'
NotEmpty behavior. CreatePlaylist coalesces null→"" at the DTO so it was an
empty-name persist, not a 500; guarded the same way.
- ReplaceTemplateItems overlap validation iterated with an `item == otherItem`
record value-equality skip, so two exact-duplicate items were value-equal and
bypassed the intersection check (both persisted). Now index-based (i != j) so
duplicates register as a self-intersection and are rejected 422.
- Trimmed the unreachable 404 ProducesResponseType from POST /api/blocks/groups and
POST /api/templates/groups (a create has no parent lookup that can 404); v1.json
regenerated.
- Regression tests: all 10 name-guard paths + the duplicate-items path (19 cases).
- Docs: decisions.md entry + api-conventions.md §3b null-safe-validation bullet.

Adds DecoController (groups + decos CRUD + full-state PUT), playlist and
artist/multi-collection search picker wrappers, a PlaylistController for the
break-content playlist cascade, and PUT /api/playouts/{id}/deco. Fixes the
CreateDecoHandler missing deco-group existence check (FK 500 -> 422), matching
the CreateBlock/CreateTemplate precedent. ReplaceDecoRequest.ToCommand rejects
Merge on the non-mergeable sections (422).
