feat: add automated smoke test system with Trigger.dev integration

[niteshift-dev-staging]

Summary

• Implements comprehensive smoke test automation using Trigger.dev scheduled tasks
• Provides on-demand and scheduled health checks for critical Cal.diy infrastructure
• Integrates Slack notifications for test failures
• Follows Cal.diy DI patterns and Trigger.dev best practices

Features

Test Types

• database-connection: Validates Prisma database connectivity
• api-health: Tests basic API queries (user count)
• auth-flow: Verifies authentication system (session count)
• booking-flow: Checks booking system health (booking count)
• calendar-integration: Tests calendar credential access
• all: Runs complete test suite

Trigger.dev Tasks

1. On-demand task (smoke-tests.run):

   • Triggered manually via dashboard or API
   • Supports all test types
   • Configurable Slack notifications

2. Scheduled task (smoke-tests.scheduled):

   • Runs every 15 minutes automatically
   • Executes all tests
   • Notifies only on failures

Architecture

• Service Layer: SmokeTestService with full dependency injection
• Queue Configuration: Concurrency limit of 5, optimized retry policy
• Slack Integration: Formatted notifications with test results and duration
• Environment Variables: SMOKE_TEST_SLACK_WEBHOOK_URL for optional notifications

Test Plan

• Unit tests for SmokeTestService with >80% coverage
• Local Trigger.dev testing via npx trigger.dev@latest dev
• Deploy to staging and verify tasks appear in dashboard
• Test on-demand execution via Trigger.dev UI
• Verify scheduled task runs every 15 minutes
• Test Slack notifications (both success and failure)
• Verify all test types execute correctly
• Check retry behavior on transient failures
