Two-pass PII redaction with multi-country pattern packs

Pass 1: deterministic regex with Nordic/European/ECHR/Global packs
covering fødselsnummer, Swedish personnummer, Danish/Finnish CPR,
UK NI, French INSEE, IBAN, EU phones, ECHR application numbers, DOB,
and national ID label patterns.

Pass 2: LLM semantic scan (Azure OpenAI) finds names, orgs, places
and identifying descriptions missed by regex. Runs on pre-redacted
text so no raw PII reaches the LLM.

Adds region selector (Nordic/European/ECHR/Global) to the Redact UI.
Falls back gracefully when Azure is not yet configured.
