Current Behavior

When creating users via the API at POST /api/application/users, the language field validation only accepts 2-letter ISO 639-1 language codes (e.g., zh, en, fr).

This prevents users from specifying locale-specific language codes like zh-TW (Traditional Chinese - Taiwan), pt-BR (Brazilian Portuguese), or ar-SA (Saudi Arabic) even though the system has complete translation files for these locales.

When Debug=false :

{
  "errors": [
    {
      "code": "ValidationException",
      "status": "422",
      "detail": "The selected language is invalid.",
      "meta": {
        "source_field": "language",
        "rule": "in"
      }
    }
  ]
}

When Debug=true : pelican_respond.json

Expected Behavior

The API should accept locale codes in the format xx-XX (language-country) in addition to 2-letter language codes, matching the existing translation file structure in the lang/directory.

Steps to Reproduce

Attempt to create a user via API with language: "zh-TW"

curl -X POST "https://demo.pelican.dev/api/application/users" \
  -H "Authorization: Bearer your_api_key_identifier_token" \
  -H "Accept: application/vnd.panel.v1+json" \
  -H "Content-Type: application/json" \
  -d '{
    "email": "user@example.com",
    "username": "testuser",
    "language": "zh-TW"
  }'

Request fails validation because zh-TW contains a hyphen and country code
