Greptile Summary

This PR fixes a bug in Microsoft Teams webhook handling where successful webhook executions were incorrectly showing error messages. The changes implement proper response formatting and HMAC signature validation across multiple components:

1. Added a new MicrosoftTeamsConfig component with a dedicated UI for Teams webhook configuration
2. Implemented HMAC signature validation in the webhook trigger route
3. Added Teams-specific response formatting in the webhook utils
4. Updated the webhook test API to properly handle Teams webhook testing

The changes follow established patterns in the codebase for webhook providers while adding Teams-specific security requirements and response formats.

Confidence score: 4/5

1. This PR is safe to merge with standard review attention
2. The changes are well-structured and include proper security measures, but the complexity of webhook handling warrants careful testing
3. Files needing attention:
   • apps/sim/app/api/webhooks/trigger/[path]/route.ts - Verify HMAC validation logic
   • apps/sim/lib/webhooks/utils.ts - Check Teams-specific response formatting
