Description

The oneuptime_api_key resource fails during creation with "Provider produced inconsistent result after apply" error due to expires_at field format inconsistency.

Problem

When creating an API key, the provider sends wrapped DateTime format but receives unwrapped format:

Terraform sends:

{
  "_type": "DateTime",
  "value": "2030-12-31T00:00:00.000Z"
}

API returns:

"2030-12-31T00:00:00.000Z"

This causes the error:

Error: Provider produced inconsistent result after apply

When applying changes to oneuptime_api_key.this, provider 
"provider[\"registry.terraform.io/oneuptime/oneuptime\"]" produced an
unexpected new value: .expires_at: was
cty.StringVal("{\"_type\":\"DateTime\",\"value\":\"2030-12-31T00:00:00.000Z\"}"),
but now cty.StringVal("2030-12-31T00:00:00.000Z").

Expected Behaviour

The provider should either:

Send unwrapped format to match API response, OR
Receive wrapped format from API to match what was sent

Reproduction

resource "oneuptime_api_key" "test" {
  project_id = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
  name       = "test-key"
  expires_at = jsonencode({
    _type = "DateTime"
    value = "2030-12-31T00:00:00.000Z"
  })
}

Run terraform apply - fails with inconsistent result error.

Workaround Attempted

Using lifecycle { ignore_changes = [expires_at] } doesn't help because the error occurs during initial creation, not updates.

Environment

Terraform: >= 1.12.0
Provider: oneuptime/oneuptime v9.4.7

Similar issue with #2247 (status_page_domain SSL fields)
