feat: validate and auto-scrape custom URLs

Changes:
- Added validation to prevent root URLs (e.g., https://example.com or https://example.com/)
- Added validation to ensure custom URLs are on the same domain as the shop
- Trigger immediate scraping when custom URL is added via job queue
- Updated CustomUrlsEndpoint to accept JobQueue dependency
- Updated routes.ts to inject JobQueue into CustomUrlsEndpoint
- Enhanced API response to include job_id and scrape_status

Validation:
- Root URL check: pathname must not be empty or "/"
- Domain check: hostname must match shop domain
- Returns helpful error message with example URL

Auto-scraping:
- Creates and queues a scraping job immediately after custom URL is added
- Respects existing job queue system with concurrency control
- Returns job_id in response for tracking scrape progress

Example error response:
{
  "error": "URL cannot point to the root of the website. Please specify a specific page URL.",
  "example": "https://example.com/some-page"
}
