Enhanced Voicemail Detection, File Processing, Knowledge Base Integration, and Invoicing Updates

1. Track Voicemail Detection Cost, Configure Google and Twilio Voicemail Detection Plans

• You can now configure provider-specific settings and track voicemail detection costs through the new VoicemailDetectionCost schema at call.costs[type=voicemail-detection].
• Configure Google or Twilio voicemail detection settings using the new GoogleVoicemailDetectionPlan and TwilioVoicemailDetectionPlan schemas.

// Google configuration example
{
  "provider": "google",
  "voicemailExpectedDurationSeconds": 15  // Range: 5-60 seconds
}

{
  "provider": "twilio",
  "enabled": true,

  "voicemailDetectionTypes": ["machine_end_beep", "machine_end_silence"]
}

2. Improved File Processing Statuses and Parsed Text Content
