fix(ci): run all test jobs when invoked via workflow_call

When staging-ci.yml calls test.yml as a reusable workflow, the event
name is the caller's event (workflow_dispatch/schedule), not push or
pull_request. This caused telegram-tests, windows-build, wasm-wit-compat,
and docker-build to be skipped during staging promotion.

Add github.event_name == 'workflow_call' to each gated job's condition.
