feat(schedule): enhance schedule tasks with web search and batch generation support

Browse Source 
Add enable_web_search and generate_count columns to schedule_tasks table.
Refactor schedule task service to publish generation jobs to RabbitMQ
instead of inline execution, supporting batch dispatch and backpressure
awareness via scheduler process.
