feat: implement phase 5 settlements and i18n support

- Add English/Spanish translation system for UI pages - Add bilingual AI audit notes using translation LLM chains in n8n - Support zero-trust Docker routing to dev stack via internal hostnames - Quiet down Next.js database query and middleware logging in test runs

+## 7. Internationalization (i18n) Architecture
+
+The internationalization architecture provides bilingual support (English and Spanish) across the application, separating client-side UI translations from AI audit translation flows.
+
+### 7.1. Client-Side Translation Context
+* **Scaffolding**: Static JSON dictionaries map UI strings under `src/lib/i18n/dictionaries/`.
+* **State Management**: A React Context provider (`LocaleProvider`) coordinates the selected locale across the client components, utilizing local storage for persistence.
+* **Component Translation**: UI components call a lightweight `t(key)` translation hook, dynamically rendering headers, tables, validation warnings, and labels.
+
+### 7.2. Bilingual AI Audit Translation Flow
+To maintain semantic accuracy and structured parsing within the n8n pipelines, AI audits execute in English, followed by a dedicated translation stage:
+
+```mermaid
+graph LR
+    Engine[Next.js API] -->|Calculated Data| n8n[n8n Workflow]
+    n8n -->|Step 1: Audit in EN| LLM[LLM Node]
+    LLM -->|Audit Notes in EN| Trans[LLM Translation Node]
+    Trans -->|Translate to EN & ES| Output[Bilingual JSON Object]
+    Output -->|Callback Save| NextDb[Next.js Database API]
+```
+
+* **Storage**: Localized AI outputs are transmitted as JSON objects:
+  ```json
+  {
+    "en": "Audit warning: High commission payout.",
+    "es": "Advertencia de auditoría: Pago de comisión alto."
+  }
+  ```
+  These are stored in the database as PostgreSQL `JSONB` fields (`flaggedReason` on `SalesResult`, and `aiAuditNotes` on `Settlement`).
+* **Rendering**: The frontend page renders the string corresponding to the user's active locale: `item.aiAuditNotes[locale]`.

+### FEATURE 8 — Internationalization & Multi-language Support
+
+#### US-COM-015 — Internationalization of UI and AI Audit Notes
+* **Role:** User / Auditor
+* **Goal:** Toggle application language and read AI audit observations in the active locale
+* **Benefit:** Support bilingual corporate workflows (English and Spanish).
+* **Acceptance Criteria:**
+  * **Scenario 1 (UI Translation):** Given that the user selects English/Spanish from the language picker, when the page renders, then all headers, buttons, form labels, and table cells must translate accordingly.
+  * **Scenario 2 (Bilingual AI Notes):** Given that n8n runs compliance audits or anomaly checks, when the workflow posts callback results, then the system must store bilingual notes and render the language matching the user's active locale.
+* **Operations (Sub-features):**
+  * Language selector dropdown, Bilingual translation dictionaries, Localized AI translation nodes, JSONB database storage.
