test(hooks): integration coverage — e2e, rbac, tracing, chaos

Adds cross-cutting integration tests exercising hooks RPC surface:

- hooks_e2e_test: create → dispatcher fire → audit entry → history list
- hooks_rbac_test: tenant-scope guard, master-only global scope enforcement
- hooks_tracing_test: audit entries include handler timing + outcome
- hooks_chaos_test: handler timeout behavior, on_timeout block/allow paths
- hooks_pipeline_test: extends existing pipeline coverage
