[20582] Cal.com Update to V2 version (#20698)

* [20582] Cal.com Update to V2 version

Describe the bug
Cal.com's deprecated V1 API endpoints are still being used internally, causing integration failures. Despite V1 being marked as deprecated, the system continues to make calls to V1 endpoints, resulting in errors when attempting to use Cal.com integrations.
To Reproduce
Steps to reproduce the behavior:

Set up any Cal.com integration
Attempt to trigger an action that uses the Cal.com API that arent V2 (e.g., create booking, fetch availability, sync calendars)
Observe that the integration fails with errors
Check the API calls being made - they reference deprecated V1 endpoints

Expected behavior
All Cal.com integrations should use the current V2 API endpoints. When V1 was deprecated, all internal systems and integrations should have been migrated to V2 to ensure continued functionality.

Additional context
Cal.com announced the deprecation of their V1 API, but appears to still be relying on V1 endpoints in their current implementation. This creates a critical issue where:

Integrations fail automatically
Users cannot reliably connect Cal.com with other services
The deprecation appears incomplete, leaving users with broken functionality

This needs to be addressed by completing the migration from V1 to V2 across all Cal.com systems and integrations.
