fix: Correct context-generator import path in SearchRoutes

The /api/context/inject endpoint was using an incorrect relative import
path for context-generator.cjs. Since SearchRoutes is in
src/services/worker/http/routes/, the correct path to reach
src/services/context-generator.ts is ../../../context-generator.js

This fixes the session start context injection issue where the hook
would print correctly but no context would load in the session.
