fix(WP-0014/A2): continued type-correctness fixes and Tailwind CSS output

- Schema.sql: add FK constraints for phases 6–12 so IHP generates Id X
  instead of UUID for FK columns (widget_adapter_specs, friction_scores,
  hub_routing_rules, agent_proposals, hub_capability_manifests, etc.)
- HubHealth, ModelRouter, ApiInteractionEvents: remove toUUID() wrappers
  now that FK columns carry proper Id types
- FederatedGovernance/Dashboard, HubRoutingRules/Index: same Id comparison fix
- AgentProposals/Index, DecisionRecords/Index, ApiConsumers/Edit: Id type fixes
- BottleneckDetector: add Data.Coerce import; CrossHubPropagation: add guard
- ApiKeys: qualify cryptohash-sha256 import to resolve package ambiguity
- WebhookDeliveryJob: use LBS.fromStrict; remove duplicate diffUTCTime
- Sessions/New: use renderFlashMessages (IHP built-in)
- ArchiveRecords/LineageInspector: simplify renderChainStep signature
- static/app.css: Tailwind CSS output (2011 lines) — A3 confirmed
- workplans/IHUB-WP-0015-local-deployment-intro-ui.md: add workplan

+# IHUB-WP-0015 — Local Deployment: Intro and Tutorial Web UI
+
+## Goal
+
+Deploy inter-hub locally and add the public-facing intro/tutorial web
+interface so that the running instance presents both a self-contained
+introduction to the framework and access to the management UI — with no
+domain extensions registered yet.
+
+## Background
+
+Depends on IHUB-WP-0014 (clean build, Tailwind CSS, admin user). Once the
+pre-flight gaps are closed, this workplan adds the missing web layer: a
+landing page, capabilities overview, and domain-extension tutorial as actual
+rendered pages within the IHP app — surfacing the rich content already in
+`docs/` and `specs/` through the web interface rather than only as files.
+
+The management UI (58 controllers, all dashboards) already exists and needs
+no new code — only a navigational entry point.
+
+## Tasks
+
+### B1 — Create `StaticPages` controller
+New `Web/Controller/StaticPages.hs` with actions:
+`LandingAction`, `CapabilitiesAction`, `TutorialAction`, `ExtensionGuideAction`.
+No auth guard — these pages are public. Register routes in `Web/Routes.hs`.
+
+### B2 — Landing page view
+`Web/View/StaticPages/Landing.hs` — what inter-hub is, the traceability chain
+(Widget → InteractionEvent/Annotation → RequirementCandidate → Requirement →
+DecisionRecord → DeploymentRecord → OutcomeSignal → Learning), key capabilities
+at a glance, and two CTAs: "Explore Capabilities" + "Go to Management UI".
+Content drawn from `SCOPE.md` and `ARCHITECTURE-LAYERS.md`.
+
+### B3 — Capabilities page view
+`Web/View/StaticPages/Capabilities.hs` — the 12-phase capability map, GAAF
+scorecard (3.68 Strong), the API surface (v1 + v2), the learning loop, the
+type registry system, and the hub federation model. Structured HTML with
+section anchors. Draws from `ARCHITECTURE-LAYERS.md` and
+`specs/InteractionHubFrameworkSpecification_v0.2.md`.
+
+### B4 — Tutorial and extension guide views
+`Web/View/StaticPages/Tutorial.hs` — step-by-step overview of how the IHF
+works from a developer perspective (Widget lifecycle, governance flow, outcome
+loop).
+`Web/View/StaticPages/ExtensionGuide.hs` — how to build and register a domain
+hub extension: HubCapabilityManifest, type registry entries, hub-owned widget
+types, hub-scoped controllers. Content drawn from
+`docs/domain-hub-extension-guide.md`.
+
+### B5 — Update root route
+Change `GET /` from `HubsAction` to `LandingAction` in `Web/FrontController.hs`
+or `Web/Routes.hs`. Management entry point becomes `GET /hubs`.
+
+### B6 — Navigation integration
+Add "Docs" / "About" / "Tutorial" links to the existing nav bar in
+`Web/FrontController.hs`. Add "Management" link pointing to `/hubs`.
+Ensure the nav is accessible from all static pages without requiring login.
+
+### B7 — Final deployment run and verification
+With WP-0014 complete: confirm `devenv up` is clean, log in as admin, walk
+the full intro → capabilities → tutorial flow, enter the management UI,
+create a test hub, verify all dashboards load. Document the local URL, admin
+credentials location, and any operational notes.
+
+## Exit Criteria
+
+- `http://localhost:8000` shows the landing page (no login required)
+- Landing → Capabilities → Tutorial → ExtensionGuide navigation works
+- "Management UI" link from landing takes authenticated users to `/hubs`
+- Hub management, all dashboards, and API v2 remain functional
+- No domain extensions pre-registered (clean starting state confirmed)
+- All pages render with correct Tailwind styling
