## What Was Built

Two admin overview pages that previously showed only pending items now support full-status views:

**Admin-Mitgliedschaften** (`/dashboard/admin-memberships`):
- Tab "Ausstehende Anträge" — existing card view with approve/reject buttons (PENDING only)
- Tab "Aktive Mitgliedschaften" — table of ACTIVE memberships
- Tab "Alle" — table of all memberships across all statuses
- User-friendly status labels: PENDING → "Ausstehend", ACTIVE → "Aktiv", INACTIVE → "Inaktiv"

**Admin-Benutzerverwaltung** (`/dashboard/approvals`):
- Tab "Ausstehende Anträge" — existing table with approve/reject (PENDING only)
- Tab "Alle Benutzer" — table of all users with status badges (no action buttons)
- User-friendly status labels: PENDING → "Ausstehend", APPROVED → "Freigeschaltet", REJECTED → "Abgelehnt"

**Backend APIs added:**
- `GET /api/community/admin/memberships` — returns all memberships with details (admin-only)
- `GET /api/admin/users` — returns all users sorted by creation date (admin-only)

└──────────────────────────────────────────────────┘
```

Pattern follows existing architecture: repository → service → controller, with `@PreAuthorize("hasRole('ADMIN')")` on all new endpoints.

## Design Decisions

1. **Reused `PendingMembershipResponse` for all-memberships view.** The existing DTO already contained all needed fields (user name/email, community, metering point, priority, status). Added `validFrom`/`validTo` fields to complete it rather than creating a new DTO.

2. **`createdAt` field on User entity.** The plan called for `findAllByOrderByCreatedAtDesc()` — this requires a sortable timestamp. Added `createdAt` with automatic `@PrePersist` initialization in `AuthService.register()`, and backfilled for existing users via `AdminDataInitializer`.

3. **Tab-based navigation pattern.** Both components use Angular signals (`activeTab`) to switch between views within the same page, keeping the existing "pending" workflow intact while adding "all" views. No new routes needed.

4. **Lazy loading for all-data tabs.** Tab content is fetched on first activation (not on page load), avoiding unnecessary API calls when the admin only needs pending items.

5. **Out-of-scope fix in `user-tariff.ts`.** An unrelated bug fix (AuthService injection + `getCurrentUserId()` replacing `tariff.sourceMeteringPointId!`) was bundled in. Should ideally be split to a separate commit per Conventional Commits scope rules.

## Usage

### Backend API

```bash
# All memberships (admin only)
curl -H "Authorization: Bearer <admin-jwt>" \
  http://localhost:8080/api/community/admin/memberships

# All users (admin only)
curl -H "Authorization: Bearer <admin-jwt>" \
  http://localhost:8080/api/admin/users
```

### Frontend

1. Start backend: `.\mvnw spring-boot:run -pl eeg_backend -Dspring-boot.run.arguments=--spring.profiles.active=dev`
2. Start frontend: `cd eeg_frontend && ng serve`
3. Log in as admin → navigate to Dashboard
4. Click "Mitgliedschaften" → see tabs: Ausstehende | Aktive | Alle
5. Click "Benutzerverwaltung" → see tabs: Ausstehende | Alle

## Verification

| Check | Result |
|-------|--------|
| Backend unit tests | 193/193 passed (BUILD SUCCESS) |
| Frontend unit tests | 68/68 passed across 17 test files |
| Frontend build | OK (budget warning only, pre-existing) |
| Typecheck | No errors |
| Integration tests | All existing REST API tests pass |
| Manual UI check | Tab navigation renders correctly, tables display data |

Non-fatal: Two unhandled HTTP errors in `dashboard-layout.spec.ts` (notification API calls to `localhost:8080` failing without running backend — expected behavior, not a regression).

## Journey Log

| # | Date | Event | Outcome |
|---|------|-------|---------|
| 1 | 2026-07-23 | Implementation — 15 tasks across 6 parallel worktrees | All tasks completed. Backend: createdAt field, repository queries, services, controllers, DTOs, tests. Frontend: OpenAPI spec, API client, tab components, tests. |
| 2 | 2026-07-23 | Integration — 8 merge batches into master | Zero merge conflicts. All branches cleanly integrated via `git merge --no-ff`. |
| 3 | 2026-07-23 | Verification — typecheck + full test suite | 193 backend + 68 frontend tests pass. Build succeeds. No regressions. |
| 4 | 2026-07-23 | Review — automated code review | Ready to merge. Two important findings: out-of-scope fix in user-tariff.ts, inconsistent Swagger annotation style in MembershipController. No blockers. |
| 5 | 2026-07-23 | Final consolidation — this report | Canonical final state written. |

## Review Notes (pre-existing, not introduced by this change)

- Frontend budget warning (954.92 kB > 500 kB limit) — pre-existing
- `AdminIamService.getPendingUsers()` lacks `@Transactional(readOnly = true)` — pre-existing
