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 DecoTemplateController mirroring TemplateController: CRUD for deco
template groups, deco templates (flat list + by-id), item listing, and a
full-replace PUT for a deco template's item list.
Hardening (deviation from a literal port of the existing handlers, matching
the #144 S2 fix for ReplaceTemplateItemsHandler):
- CreateDecoTemplateHandler now validates DecoTemplateGroupId exists before
insert (previously a bad id hit the FK constraint at SaveChanges and
surfaced as a 500; now a 422).
- ReplaceDecoTemplateItemsHandler now rejects invalid items (unknown DecoId,
StartTime >= EndTime unless EndTime is the end-of-day sentinel 00:00:00,
or overlapping ranges) with a 422 instead of silently dropping/persisting
them - the same silent-drop/silent-overlap bug class already fixed for
templates.
Response DTOs serialize the raw item TimeSpans (via .TimeOfDay), so an
end-of-day item still round-trips as StartTime=22:00:00/EndTime=00:00:00
regardless of the ViewModel's day-wrapping DateTime representation.
