feat: aws_uxc_account_customizations resource and aws_uxc_services data source

[alexbacchin]

Description

Blog Post:
Customize your AWS Management Console experience with visual settings including account color, region and service visibility

• Announcement

Adds support for the Amazon User Experience Customization (UXC) service to the Terraform AWS Provider.

Although the UXC API documentation contains ‘GetAccountColor‘ and ‘PutAccountColor‘, the UXC Go AWS SDK v2 does not support these actions

This PR introduces:

• Resource: aws_uxc_account_customizations - Manages account customization settings including account color and visibility of regions/services
• Data Source: aws_uxc_services - Lists all available UXC services for an account

Example Usage

Account Customizations Resource

# Set account color and restrict visible services
resource "aws_uxc_account_customizations" "example" {
  account_color    = "teal"
  visible_services = ["service1", "service2"]
}

# Clear all restrictions (explicit empty lists)
resource "aws_uxc_account_customizations" "unrestricted" {
  account_color    = "none"
  visible_regions  = []
  visible_services = []
}

Services Data Source

# Fetch list of all available services
data "aws_uxc_services" "available" {}

output "uxc_services" {
  value = data.aws_uxc_services.available.services
}

Relations

Closes #44033
Depends on #47114

Changes Made

• Account customizations resource with CRUD operations and import support. The UXC API does not provide a delete operation. Destroying this resource resets all customizations to their defaults: account_color is set to none, and both visible_regions and visible_services are cleared to allow all regions and services.
• Services data source with pagination support
• Comprehensive acceptance tests for both resource and data source

Code Generation Disclosure

AI was used to assist with scaffolding, code generation guidance, and PR preparation. All code has been reviewed and is understood by the submitter.

Output from Acceptance Testing

Acceptance tests require a valid AWS account. All tests are marked serial as they
operate on account-scoped state.
