Merge pull request 'Implement WooCommerce publishDraft flow' (#2) from feature/wp-publish-draft into main

Reviewed-on: #2
## publishDraft Implementation Review

### 1. Cleanup Suggestions

**None.** After thorough review:

- **Production code** (39 lines total): Clean, minimal, correct. The `publish_status.dart` import is used by `updateProductStatus`. No dead code, no unused imports. `flutter analyze` reports zero issues.
- **Test code**: The `publishDraft` and `updateProductStatus` groups each have their own local JSON builder helper. The slight duplication is intentional — each is scoped to its group with the right defaults. No cleanup needed.
- **Static analysis**: Both `feature_wordpress` and `kell_web` pass `flutter analyze` with zero issues.
- **Dashboard test stub** (`_StubProductPublishingRepository.publishDraft` still throws `UnimplementedError`): Correct — the dashboard never calls `publishDraft`, so the stub is never exercised. No change needed.

### 2. Test Gaps Worth Adding (optional, not blocking)

| Gap | Priority | Rationale |
|-----|----------|-----------|
| `publishDraft` with 404 (product not found) | Low | Already covered implicitly by `WooCommerceApiClient.updateProduct` error handling, but an explicit 404 test would document the "missing product" scenario |
| `publishDraft` verifies auth header is present | Low | Auth is tested at the `WooCommerceApiClient` level already; adding it here would be redundant |
| `publishDraft` on already-published product (idempotency) | Low | Tests WooCommerce behavior, not our code |

None of these are blocking.

### 3. PR Readiness

**✅ Ready for merge.**

Evidence:
- `flutter analyze` — 0 issues on both packages
- `flutter test` — 99 pass (feature_wordpress), 24 pass (kell_web)
- 2 files changed, ~15 lines of net production code
- No architectural changes, no composition changes, no credential exposure
- Strict package boundaries preserved
- Runtime config via `--dart-define` unchanged
