Refactor: Extract common IAM logic into shared weed/iam package (#7747)
This resolves GitHub issue #7747 by extracting duplicated IAM code into a shared package that both the embedded S3 IAM and standalone IAM use. New shared package (weed/iam/): - constants.go: Common constants (charsets, action strings, error messages) - helpers.go: Shared helper functions (Hash, GenerateRandomString, GenerateAccessKeyId, GenerateSecretAccessKey, StringSlicesEqual, MapToStatementAction, MapToIdentitiesAction, MaskAccessKey) - responses.go: Common IAM response structs (CommonResponse, ListUsersResponse, CreateUserResponse, etc.) - helpers_test.go: Unit tests for shared helpers Updated files: - weed/s3api/s3api_embedded_iam.go: Use type aliases and function wrappers to the shared package, removing ~200 lines of duplicated code - weed/iamapi/iamapi_management_handlers.go: Use shared package for constants and helper functions, removing ~100 lines of duplicated code - weed/iamapi/iamapi_response.go: Re-export types from shared package for backwards compatibility Benefits: - Single source of truth for IAM constants and helpers - Easier maintenance - changes only need to be made in one place - Reduced risk of inconsistencies between embedded and standalone IAM - Better test coverage through shared test suite
