* feat(event-reporters): restore codefresh-sa service account for backward compatibility

- Add event-reporters.workflow.serviceAccount configuration to values.yaml

- Add helper functions for workflow reporter service account in _helpers.tpl

- Create workflow-reporter-sa.yaml template to provision codefresh-sa service account

- Maintains backward compatibility with e2e tests and existing workflows

- Service account created only when event-reporters.workflow.serviceAccount.create is true

- Defaults to 'codefresh-sa' name when no custom name is specified

Resolves e2e test failures due to missing codefresh-sa service account after event-reporters removal.

* feat(event-reporters): add RBAC permissions for codefresh-sa service account

- Create workflow-reporter-rbac.yaml with Role and RoleBinding

- Grants full namespace permissions (all apiGroups, resources, verbs)

- Restores same permissions as original workflow-reporter service account

- Ensures backward compatibility for e2e tests requiring elevated permissions
