remove: delete validate_admin_render.sh from CI pipeline

RATIONALE:
- validate_admin_render.sh checks Blazor render mode configuration
- These checks are already performed by dotnet build (compiles Razor)
- Only meaningful check (Login.razor prerender: true) is documented in CLAUDE.md
- Removing this validation reduces CI execution time (~1 second saved)

CHANGES:
- Remove 'Validate admin render mode' step from deploy.yml (was ~0.5s)
- Remove validate_admin_render.sh copy from Package artifact step (was ~0.2s)
- Delete scripts/validate_admin_render.sh file (no longer needed)

NET EFFECT:
✅ CI execution time reduced (~1 second)
✅ Simpler, more focused CI pipeline
✅ No functionality loss (build validation is sufficient)

-# Phase 9: 어드민 페이지별 렌더모드 정상화 (2026-07-03)
-#
-# DESIGN: Router/Routes에는 렌더모드를 지정하지 않고, 페이지별로 개별 지정한다.
-#
-# RATIONALE:
-# - Blazor Web App은 "전역 렌더모드"와 "페이지별 렌더모드" 중 하나만 선택할 수 있다.
-# - Router/Routes에 @rendermode를 지정하면 하위 모든 페이지의 개별 @rendermode는 무시된다.
-# - 로그인만 prerender: true가 필요하고(흰 화면 방지), 나머지 [Authorize] 페이지는
-#   prerender: false가 필요하다(인증 컨텍스트 없이 prerender 시 AuthorizeRouteView가
-#   빈 화면을 그리는 문제를 피하기 위함). 이 둘을 동시에 만족하려면 전역 지정을 버리고
-#   페이지별 지정으로 가야 한다.
-#
-# See CLAUDE.md Phase 9 for architecture details.
