Improve integration test coverage for role package

[sajitha-tj]

Purpose

Improve integration test coverage for the backend/internal/role package.

Approach

Added tests/integration/role/roleapi_test.go extensions and a new tests/integration/role/role_authz_test.go with TestRoleAuthzTestSuite, plus a supporting model.go for role test fixtures. TestRoleAPITestSuite now covers 67 top-level cases (previously a smaller set), adding error paths, filter/pagination edge cases, dependency-delete guards, and cross-store declarative role behavior for /roles.

Measured integration coverage after this change:

Package / file	Coverage	Statements
internal/role	79.1%	1552/1962

Remaining uncovered paths are mostly error/unreachable branches: the file-based store's stub cascade-delete paths, the composite store's IsRoleDeclarative variant in store.go, and ResolveForRole in permission_resolver.go.

📝 Walkthrough

Walkthrough

The PR adds role models and a declarative role fixture. It expands integration coverage for role API validation, authorization, organization-unit roles, agent assignments, access evaluation, and role export.

Changes

Role API and authorization coverage

Layer / File(s)	Summary
Role contracts and declarative fixtures tests/integration/role/model.go, tests/integration/resources/.../role-declarative-1.yaml	Adds models for role listings, exports, group members, access evaluation, and member requests. Updates the declarative role fixture with an OU handle, permission, and assignments.
Role authorization suite tests/integration/role/role_authz_test.go	Adds fixtures and tests for system-permission requirements and group membership authorization.
Role API validation and listings tests/integration/role/roleapi_test.go	Adds coverage for validation, routing, CORS, pagination, agent assignments, organization-unit listings, and role mutability.
Declarative roles, evaluation, and export tests/integration/role/roleapi_test.go	Adds coverage for declarative role behavior, assignment merging, access evaluation, and explicit or wildcard exports.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to 112d4

The PR expands role integration coverage without changing production behavior, but one group-filtered pagination assertion may intermittently fail when result ordering is not deterministic; it is mergeable with explicit owner follow-up to enforce stable ordering.

2140-2158, 2196-2200, and 2186-2194, update the deferred cleanups to assert
errors with suite.NoError instead of discarding them: apply this to both
removeAssignments calls and the testutils.DeleteUser call, ensuring each leaked
shared fixture causes the originating test run to fail.

Apply the same fix in `@tests/integration/role/roleapi_test.go` around lines 2186
- 2194.
- Around line 2010-2020: Add ASSIGNEE_ID as a secondary tie-breaker to the
assignment query ORDER BY clauses, after CREATED_AT, so pagination remains
stable when timestamps match. Preserve the existing page-count checks and
distinct assignment ID assertion in the role assignment test.
