feat(iace): wire crossref into tech-file, library UI, and contract tests

Three follow-ups to the 671-norm cross-reference matrix:

1. Tech-file renderer (Go): standards_applied section now gets a deterministic
   Markdown appendix with the DIN/ANSI/GB/JIS mappings for the project's
   suggested norms. Built from registry, never hallucinated by LLM. Applied
   both to LLM and fallback content paths.

2. Frontend NormCrossRefPanel (Next.js): expandable row in the IACE library
   norms tab now has a "Internationale Aequivalenzen anzeigen" button that
   lazy-loads /iace/norms-library/:id/crossref and renders a colour-coded
   table (relation + confidence). Region labels humanised (US — ANSI,
   China (GB), Japan (JIS), etc.).

3. Contract tests (Go): 4 new handler tests pinning the response shape of
   GetNormCrossRef and ListNormCrossRefs. Equivalent to an OpenAPI snapshot
   for these specific endpoints — ai-compliance-sdk has no full OpenAPI
   baseline yet (separate ticket).

Tests: 6 renderer tests + 4 handler contract tests, all green.

+P31 — Tiered LLM-Cascade mit Confidence + Valkey-Cache.
+
+Bisherige LLM-Calls (vendor_llm_extractor, mc_solution_generator):
+* gehen direkt an Qwen lokal → bei kompliziertem Input lange Latenz
+* fallen bei Fail manuell auf OVH 120B zurueck
+* Kein Cache → gleiche Eingabe kostet x-mal Zeit
+
+Diese Modul vereinheitlicht:
+1. Cache-Lookup (md5(prompt) → cached response, TTL 7d)
+2. Qwen-Aufruf mit kurzem Timeout (90s)
+3. Wenn fail/leer ODER confidence < threshold → OVH 120B (45s)
+4. Wenn auch fail → Anthropic Claude (last resort)
+5. Response wird gecached
+
+confidence-Heuristik:
+* parsed JSON erfolgreich + non-empty → 0.8
+* JSON-Parse failed → 0.0
+* JSON ok aber nur 1 Item bei >5000 chars input → 0.3
