test(e2e): Add E2E tests for consumer and credentials (#3243)

* feat(e2e): add E2E tests for Consumers resource

- Add Page Object Model for Consumers (e2e/pom/consumers.ts)
- Add list and pagination tests (consumers.list.spec.ts)
- Add CRUD tests with required fields (consumers.crud-required-fields.spec.ts)
- Add CRUD tests with all fields (consumers.crud-all-fields.spec.ts)
- Add deleteAllConsumers() helper function in src/apis/consumers.ts

All tests follow the established pattern:
- *.list.spec.ts for list page and pagination
- *.crud-required-fields.spec.ts for basic CRUD operations
- *.crud-all-fields.spec.ts for comprehensive CRUD with all fields

Tests cover:
- Navigation and page assertions
- Form validation
- Create, Read, Update, Delete operations
- Labels management with tags input
- Pagination with table controls and URL params

Fixes username validation by using only allowed characters [a-zA-Z0-9_-]

* feat: add e2e tests for consumer credentials

- Add credentialsPom for page object model
- Add comprehensive test suite for credentials CRUD operations
- Test credential isolation between consumers
- Test empty state handling
- Configure serial mode to avoid race conditions

All 8 tests passing
