Fix GoHighLevel & Base44 Call Tracking and Webinar Analytics Integrations

Fix and troubleshoot two existing Base44/GoHighLevel tracking platforms. The work included resolving call tracking issues so call duration and voicemail data are passed correctly from GoHighLevel into Base44, improving IVR audio playback so the message starts immediately, and filtering the workflow to the correct phone number. The second part involved fixing webinar analytics tracking, including visitor tracking, opt-in name/email capture, sales page visits, session matching, anonymous visitor tracking, and webinar watch-time/drop-off tracking across GoHighLevel funnel pages.
