CDC (Change Data Capture) Configuration Page

Create an Angular page for configuring and monitoring Change Data Capture using the existing CdcConfig and CdcPublisher infrastructure.

Backend Endpoints Needed

GET    /admin/cdc/status          — Current CDC configuration & status
PUT    /admin/cdc/config           — Update CDC config (enabled, endpoint)
GET    /admin/cdc/events          — Recent CDC events (if collector mode)
GET    /admin/cdc/stats           — Events published, failures, throughput

UI Requirements

Status Overview

• Mode: Collector vs Webhook publisher
• Endpoint: Display configured webhook URL
• Connected: Last successful publish timestamp

Configuration

Acceptance Criteria
