chore(deps): bump project-engine-client to 1.15.0 (LLMO-6274)

[aliciadriani]

What

Bumps @adobe/spacecat-shared-project-engine-client 1.14.0 → 1.15.0 (package.json + lockfile only).

Why

This is the dependency bump #2862 (WP-O2a) explicitly deferred — "the PE-client dependency bump to the WP-O1 release is deferred until that release exists." WP-O1 is now released (1.15.0), so this lands it.

It unblocks the it-postgres serenity gate-3 validation of the tolerant origin/source authorship-root resolver. The IT harness pins the Semrush mock image tag to the installed client version (test/it/postgres/setup.js → SERENITY_PE_MOCK_TAG, exact match, no fallback). The origin root rename + legacy-source-workspace seed that the gate-3 cases run against shipped only in 1.15.0 (WP-O1, spacecat-shared 3ead32b / LLMO-6273). While main pinned 1.14.0, the harness pulled the pre-rename mock and gate-3 could not be exercised (the renamed ['category','intent','origin','type'] assertion would fail; no legacy fixture to adopt).

With this bump the harness derives SERENITY_PE_MOCK_TAG=1.15.0, so the CI it-postgres job now exercises:

• existing origin root resolves;
• legacy source root (children ⊆ {ai,human}) adopted in place, no 2nd root minted;
• fresh project mints origin;
• membership (not set-equality) assertions in childrenAreAuthorship.

Risk

Mock-only release. 1.15.0 over 1.14.0 touched only the package's mock/ dir — the client runtime and typings are unchanged, so there is no production behavior change (no coordinated merge window needed, unlike the rename in #2862). Lockfile delta is the single package entry.

Verification

• npm run type-check ✅ (clean)
• Lockfile + node_modules resolve to 1.15.0 ✅
• Real gate-3 e2e validation runs here in CI (it-postgres has ECR access for the private data-service image).

Hey @aliciadriani,

⚠ Degraded review - no spec document was found for this change (searched the PR links, the touched repos' docs, the architecture/guidelines docs, and linked Jira). This review covers code-level quality but could not validate the change against an agreed design, so confidence is reduced. Add a spec link (PR template section 4) and re-request review for a full-confidence pass.

Verdict: Approve - clean dependency bump, no issues found.
Complexity: LOW - trivial diff; dependency signal.
Changes: bumps @adobe/spacecat-shared-project-engine-client from 1.14.0 to 1.15.0 in package.json and lockfile (2 files).
