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
