feat(domain): Domain\Scontainers + Domain\Banners repositories z wrapper delegation

Phase 3 complete:
- ScontainersRepository: containerDetails, containerSave, containerDelete, scontainerByLang
- BannersRepository: bannerDetails, bannerSave, bannerDelete, activeBanners, mainBanner
- 4 legacy factories converted to thin wrappers delegating to Domain repos

+# Phase 3 Plan 01: Scontainers + Banners Repositories Summary
+
+**Domain repositories for Scontainers and Banners with wrapper delegation in all 4 legacy factories.**
+
+## Performance
+
+| Metric | Value |
+|--------|-------|
+| Duration | ~2min |
+| Tasks | 2 completed (delegated) |
+| Files created | 2 |
+| Files modified | 4 |
+
+## Acceptance Criteria Results
+
+| Criterion | Status | Notes |
+|-----------|--------|-------|
+| AC-1: ScontainersRepository exists with all methods | Pass | 5 methods (incl. constructor), 110 lines |
+| AC-2: BannersRepository exists with all methods | Pass | 6 methods (incl. constructor), 148 lines |
+| AC-3: Legacy admin factories delegate to repositories | Pass | 6 static methods → thin wrappers |
+| AC-4: Legacy front factories delegate to repositories | Pass | 3 static methods → thin wrappers, $lang[0] passed explicitly |
+
+## Accomplishments
+
+- Created ScontainersRepository with containerDetails, containerSave, containerDelete, scontainerByLang
+- Created BannersRepository with bannerDetails, bannerSave, bannerDelete, activeBanners, mainBanner
+- Established wrapper delegation pattern — first usage in the project, template for all future phases
+
+## Files Created/Modified
+
+| File | Change | Purpose |
+|------|--------|---------|
+| `autoload/Domain/Scontainers/ScontainersRepository.php` | Created | Domain repository for scontainers CRUD + cached front read |
+| `autoload/Domain/Banners/BannersRepository.php` | Created | Domain repository for banners CRUD + cached active/main banner |
+| `autoload/admin/factory/class.Scontainers.php` | Modified | Wrapper: 3 methods delegate to ScontainersRepository |
+| `autoload/admin/factory/class.Banners.php` | Modified | Wrapper: 3 methods delegate to BannersRepository |
+| `autoload/front/factory/class.Scontainers.php` | Modified | Wrapper: 1 method delegates with $lang[0] |
+| `autoload/front/factory/class.Banners.php` | Modified | Wrapper: 2 methods delegate with $lang[0] |
+
+## Decisions Made
+
+| Decision | Rationale | Impact |
+|----------|-----------|--------|
+| Wrapper creates new repo instance per call | Matches static factory pattern, no singleton needed | Simple, no state leaks between calls |
+| Front repos use CacheHandler, not \Cache | Aligns with Shared layer conventions | Consistent caching across Domain layer |
+| $lang[0] passed as parameter, not global in repo | Repositories should not depend on globals | Cleaner, testable API |
+
+## Deviations from Plan
+
+None — plan executed exactly as written.
+
+## Issues Encountered
+
+None.
+
+## Next Phase Readiness
+
+**Ready:**
+- Domain\Scontainers and Domain\Banners available for Admin controllers (Phase 10)
+- Wrapper delegation pattern established for future Domain phases (4, 5)
+
+**Concerns:**
+- None
+
+**Blockers:**
+- None
