[MWPW-195799]Add guid to unity splunk dashboard and AA events

[Ruchika4]

Description

• Introduce generateUploadGuid() in acrobat/scripts/alloy/verb-widget.js
  using crypto.randomUUID() to generate a unique ID per upload session
• Include GUID in Splunk payload under upload.guid to enable cross-event
  correlation for a single upload session in the dashboard
• Call generateUploadGuid() on change and drop events across all three
  blocks before analytics events fire, ensuring GUID is set at upload start
• Export generateUploadGuid via window.analytics in study-marquee,
  verb-marquee, and verb-widget blocks for consistent access
• Use optional chaining (?.) when invoking to handle analytics module
  not being loaded
