feat(portal): M11.1 catalog flow + M12.1 self-serve trial

M11.1 — /[slug]/catalog page renders the live catalog from tenant-registry, gates already-owned products with an 'Active' chip, and exposes two server actions per remaining card: - Request → POST /v1/catalog/request (emits an audit event; sales follow-up flow will pick this up when M8.x lands ERPNext + the Lead webhook) - Start 14-day trial → POST /v1/catalog/trial-request (provisions the entitlement immediately; 14-day expiry per M4.2) Flash banner on success/error (?ok= / ?err= query params). M12.1 — Public /start route. Server action calls createTenant({slug, name, plan, admin_email}) → tenant-registry's KC-aware POST /v1/tenants → user lands at /<slug>/dashboard. The dashboard now renders a trial-days-left banner when status=trial and trial_ends_at is set (urgent styling when ≤3 days remain). Library: src/lib/tenant-registry.ts widened from one-call client to the full read+mutate surface (fetchCatalog, fetchEntitlements, requestProduct, startTrial, createTenant). Returns typed {ok: true, ...} | {ok: false, error: '...'} so server actions branch cleanly. 22 vitest cases, 100% line+branch+function coverage of src/lib/. Catalog tests rely on the mock-fetch pattern; the user-visible flow is exercised by Playwright when the dev stack is up. Refs: M11.1 + M12.1

 ## [Unreleased]

 ### Added
+- feat(signup): M12.1 — public /start form creates a trial tenant via POST /v1/tenants (KC adapter provisions the org + invites the admin); dashboard renders a trial-days-left banner when status=trial
+- feat(catalog): M11.1 — /[slug]/catalog renders the live catalog, gates owned products, server-action 'Request' (POST /v1/catalog/request) + 'Start 14-day trial' (POST /v1/catalog/trial-request)
 - feat(test): M5.3 — Playwright e2e harness (apex / tenant / dev-stack-health specs). pnpm e2e + make e2e. CI e2e job gated behind RUN_E2E variable until stage exists.
 - feat(app): M5.2 — customer-area route shells (settings, billing, audit, support, catalog, products, projects, settings/{users,api-keys,integrations}); shared Nav component reads session.org_roles and shows only what each role can see; backstage stub at /__backstage__; dashboard renders product tiles from session.products
 - chore(deps): bump next + eslint-config-next to 16.2.6 to clear trivy CVEs (CVE-2025-29927 critical + 7 highs in next 15.0.3)
