health.php: Add azure_search check — calls /$count endpoint and
reports doc count in the index. Reads DBN_AZURE_SEARCH_{ENDPOINT,KEY,INDEX}.
corpus-search.php: Add azure mode — semantic + vector hybrid search
via Azure AI Search bnl-legal-v2. Embeds query with LiteLLM
nomic-embed-text; expands keepCats to include government-policy,
health-law, social-services, labour-law, immigration (previously
blocked by contamination workaround, now safe to include).
