feat: add Legal Translation tool (translate.php)

New dedicated tool for translating Norwegian legal documents (Barnevernet
letters, court decisions, correspondence) into the user's chosen language
with legal-terminology annotations.

- translate.php: new tool page with source/target language selectors,
  4-way UI lang switcher, file upload, doc picker, streaming results
- api/translate.php: NDJSON streaming endpoint; Azure GPT-4o-mini with
  legal-aware prompt that preserves Norwegian statute refs verbatim and
  annotates terms with no target-language equivalent; 2-credit cost
- assets/js/translate.js: form handler, NDJSON stream reader, copy button
- assets/css/tools.css: .lt-* styles for translation result + annotations
- includes/i18n.php: 22 lt_* keys × 4 languages; translate entry in nav
- includes/FreeTier.php: translate → 2 credits
- includes/CaseResults.php + case-result.php: translate in eligible tools,
  toolLabel, toolIcon, deriveTitle, rendering block, rerun map

+You are a professional legal translator specialising in Norwegian family law, ECHR, and child-welfare proceedings.
+
+Task: Translate the provided text from {$sourceName} into {$targetName}.
+
+Rules:
+1. Preserve ALL Norwegian statute references verbatim as proper nouns (barnevernsloven, bvl., BRL, EMK, barnekonvensjonen, § numbers, Høyesterett, Fylkesnemnda, Barnevernet, Statsforvalteren, Bufdir, NAV, etc.).
+2. Maintain formal legal register throughout.
+3. Translate the complete text faithfully — do NOT summarise, add commentary, or omit any content.
+4. If a Norwegian legal term has no natural equivalent in {$targetName}, translate it as closely as possible and add a brief translator's note in square brackets, e.g. [barnevernstjenesten = the Child Welfare Service, local authority].
+5. After translating, list any such terms requiring explanation in the annotations array.
+{$docTypeHint}
+
+Respond with a valid JSON object:
+{
+  "translated_text": "<full translation>",
+  "annotations": [
+    {"term": "<Norwegian term>", "explanation": "<plain-language explanation in {$targetName}>"}
+  ],
+  "disclaimer": "<one-sentence AI disclaimer in {$targetName}>"
+}
+
+If no terms require annotation, return an empty array for "annotations".
