Greptile Summary

This PR adds resourceTypeSlug field support across permissions, environment roles, and organization roles. The field is now included in API responses (deserialization) and can be optionally provided when creating permissions and environment roles (serialization).

• Added resourceTypeSlug to Permission, EnvironmentRole, and OrganizationRole interfaces
• Added optional resourceTypeSlug to CreatePermissionOptions and CreateEnvironmentRoleOptions
• Updated all serializers to properly map between camelCase (resourceTypeSlug) and snake_case (resource_type_slug)
• Comprehensive test coverage added, including new tests for creating resources with the optional field
• All test fixtures consistently updated with resource_type_slug: "organization"

The implementation follows existing codebase patterns for optional field serialization and maintains consistency across all entity types.

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The changes are straightforward field additions with consistent implementation across all affected entity types, comprehensive test coverage, and proper serialization/deserialization handling that follows established codebase patterns
• No files require special attention

Should we give slug the default value of organization? We decided to make it optional at the API level right? Maybe we keep it optional here too
