Add entity details data source

[TomWKraken]

Add Full Entity Details to cortex_catalog_entity Data Source

Description

Enhances the cortex_catalog_entity data source to expose comprehensive catalog entity information by switching from the entity descriptor endpoint to the full entity details endpoint.

Changes

• Updates data source to use GET /api/v1/catalog/{tagOrId} instead of /api/v1/catalog/{tagOrId}/openapi
• Expands schema to expose:
• • Ownership information (emails and groups with inheritance details)
• • Slack channel associations
• • Git repository information
• • Archive status and last updated timestamp
• • Links and custom metadata
• • Additional entity identifiers (ID, tag)

Motivation

Previously, the data source only exposed basic metadata (tag, name, description). Users had no way to query entity ownership, integrations, or other critical attributes through Terraform. This enhancement enables richer entity queries and allows teams to programmatically access entity details for automation, reporting, and validation use cases.

Example Usage:

data "cortex_catalog_entity" "my_service" {
  tag = "my-service"
}

output "service_owner" {
  value = data.cortex_catalog_entity.my_service.ownership.groups[0].group_name
}

output "service_git_repo" {
  value = data.cortex_catalog_entity.my_service.git.repository
}

Breaking Changes

None. This is purely additive—all existing configurations continue to work as before. Core fields (tag, name, description) remain unchanged.

Testing

• Verified data source returns all entity details from the API
• Tested nested object and list attribute access
• Confirmed existing tests pass
• Data source successfully builds and integrates with provider

Notes

• Internal Go struct CatalogEntity.Title renamed to Name to match API response field names
• Internal Slack integration type renamed from CatalogEntitySlackChannel to CatalogEntitySlackIntegrationChannel to avoid collision with new entity response type

Overall looks good, thank you!

Minor lint fixes for CI, also might be good to have some additional unit tests around the FromApiModel changes. E.g. happy path, empty/nil collections, etc.

Actioned comments and added unit tests for the API model 🙇

awesome! i think we just need a go generate ./... for some code gen and then it's good to go!
