feat(tpsc): Third-Party Services Catalog (CUST-WP-0023)

Introduces TPSC for tracking external service dependencies with GDPR
compliance maturity (CNIL/IAPP CMMI scale), pricing model, ToS, and
data retention information across all repos.

Primary data:
- canon/tpsc/{openai,anthropic,gemini,openrouter}-api.yaml — service definitions
- tpsc.yaml in each repo (llm-connect seeded with 4 services)

State-hub additions:
- Migration j7e8f9a0b1c2: tpsc_catalog + tpsc_snapshots + tpsc_entries
- api/models/tpsc.py, api/schemas/tpsc.py, api/routers/tpsc.py
- /tpsc/catalog/, /tpsc/ingest/, /tpsc/snapshots/, /tpsc/report/gdpr endpoints
- 4 MCP tools: register_service, list_services, ingest_tpsc_tool, get_gdpr_report
- scripts/ingest_tpsc.py + make ingest-tpsc[/-all] targets
- Dashboard: tpsc.md page + docs/tpsc.md

+  OpenRouter is a US-based routing proxy for multiple LLM providers.
+  Privacy policy exists but as of early 2026 no formal DPA or SCCs are
+  publicly available. Requests are forwarded to underlying providers
+  (OpenAI, Anthropic, Google, Mistral, etc.) each with their own data
+  handling. GDPR compliance is therefore dependent on both OpenRouter
+  and the selected downstream model provider. Not recommended for
+  processing personal data in corporate/regulated environments without
+  a signed DPA. Suitable for development, prototyping, model comparison.

+  Requests forwarded to upstream providers. OpenRouter may log requests
+  for billing and abuse prevention. Retention policy not formally published.
+  Downstream provider retention policies apply per selected model.
