feat(worker): add scheduled job to refresh zalo oauth tokens daily

[sung17]

Summary

• Adds a new BullMQ scheduled job (refreshZaloTokens) that runs daily at 02:00 UTC to refresh OAuth access tokens for all Zalo integrations
• Introduces ZaloIntegrationService in @chatbotx.io/business with findAll and updateAuth methods to keep DB access out of the worker layer
• Registers the new job type in @chatbotx.io/worker-config so it is type-safe across the monorepo

Changes

• packages/worker-config/src/queues/schedule/index.ts — new refreshZaloTokens job constant and ScheduleJobRefreshZaloTokens type
• packages/business/src/integration-zalo/service.ts — new ZaloIntegrationService (findAll, updateAuth)
• packages/business/src/integration-zalo/index.ts — re-exports the new service
• apps/worker/src/schedule/handlers/refresh-zalo-tokens.ts — iterates integrations and refreshes tokens, logs per-entry results and skips entries with no refresh token
• apps/worker/src/schedule/handlers/register-schedules.ts — registers the cron scheduler (0 2 * * *)
• apps/worker/src/schedule/worker.ts — routes refreshZaloTokens job type to the handler

Test plan

• pnpm lint passes
• pnpm --filter worker check-types passes
• pnpm --filter @chatbotx.io/business check-types passes
• Deploy to staging and confirm the job appears in the BullMQ dashboard
• Manually trigger the job and verify Zalo tokens update in the database
• Confirm integrations with no refreshToken are skipped with a warning log, not crashed

Pull request overview

Adds a new scheduled BullMQ job in the worker to refresh OAuth access tokens for all Zalo integrations daily, while introducing a business-layer service to keep DB access out of the worker layer and extending the worker-config schedule job typing for monorepo safety.

Changes:

• Add refreshZaloTokens as a new schedule job type in @chatbotx.io/worker-config.
• Introduce ZaloIntegrationService in @chatbotx.io/business to list Zalo integrations and update their auth payloads.
• Register and route a daily cron (02:00) scheduled job in the worker to refresh tokens for each Zalo integration.
