feat(packages/sui-segment-wrapper): remove manual ga4 implementation

[kikoruiz]

Summary

Add backwards-compatible GA4 integration with automatic mode detection and remove deprecated Adobe Analytics integration.

Changes

Backwards-Compatible GA4 Dual-Mode Integration

Added automatic mode detection to support both manual GA4 initialization (existing) and Segment GA4 destination (new):

LEGACY Mode (when googleAnalyticsMeasurementId is configured):

• Manual GA4 initialization with gtag
• Integration name: 'Google Analytics 4' with clientId and sessionId object
• google_consents sent in context
• analytics_storage included in context
• All existing GA4 functionality preserved:
  • loadGoogleAnalytics(), getGoogleClientId(), getGoogleSessionId()
  • triggerGoogleAnalyticsInitEvent(), setGoogleUserId()
  • sendGoogleConsents() for GTM Consent Mode
  • Campaign tracking via getCampaignDetails()

NEW Mode (when googleAnalyticsMeasurementId is NOT configured):

• Segment "Google Analytics 4 Web" destination handles all GA4 functionality
• Integration name: 'Google Analytics 4 Web': true
• google_consents sent in properties (Segment best practice)
• No analytics_storage in context (handled by destination)
• No manual gtag initialization or script loading
• No "sui" init event (destination handles initialization)

Detection Logic:

• Simple synchronous config check: !getConfig('googleAnalyticsMeasurementId')
• Stateless detection on every call
• New utility: src/utils/ga4Detection.js

Key Fixes:

• integrations now sent in both main object AND context.integrations (fixed integration routing)
• google_consents location optimized based on mode: context for LEGACY, properties for NEW
• "sui" init event only fires in LEGACY mode

Adobe Analytics Removal

Removed deprecated Adobe Analytics integration (no longer used):

• All Adobe Visitor API code removed
• Backwards-compatible stubs provided:

  export const getAdobeVisitorData = () => Promise.resolve({trackingServer: '', version: ''})
  export const getAdobeMCVisitorID = () => Promise.resolve('')
