Add missing securitySettings fields to webWidgetConfig in ces_deployment

This PR adds missing fields to web_widget_config in the google_ces_deployment resource to match the REST API, and fixes some discrepancies in existing fields.

Documentation

https://docs.cloud.google.com/customer-engagement-ai/conversational-agents/ps/reference/rest/v1/ChannelProfile#ChannelProfile.WebWidgetConfig

Rationale

The web_widget_config in google_ces_deployment had limited support compared to the REST API. Specifically, securitySettings and its sub-fields were missing, which are needed for configuring allowed origins and reCAPTCHA.

Technical Details

• Added Fields: Added securitySettings with enablePublicAccess, enableOriginCheck, allowedOrigins, and enableRecaptcha to Deployment.yaml.
• Fixed Discrepancies:
  • Updated channelType to include missing values: FIVE9 and CONTACT_CENTER_INTEGRATION.
  • Updated modality to use MODALITY_UNSPECIFIED and add CHAT_VOICE_AND_VIDEO.
  • Updated theme to use THEME_UNSPECIFIED.
• Boolean Handling: Used send_empty_value: true for boolean fields to ensure false values are propagated to the API.
• Testing:
  • Created a new example file ces_deployment_full.tf.tmpl to showcase the new fields.
  • Updated ces_deployment_test.go to include update tests for the new fields, specifically testing toggling from true to false.

Verification Results

• Code generation successful for both GA and Beta.
• Acceptance tests passed successfully in both GA and Beta providers.
• Manual verification in a test project confirmed that the fields are correctly stored in the backend.
