Protect the self-hosted runner from fork code on the labeled path.

Adding test-staging is an authorization signal, but it is not a head-repository check or proof of runner isolation. The labeled path checks out the fork head and runs it on infra1-runners-arc/runners-small. Fork pull-request runs do not receive repository secrets, so this path does not establish PYTHON_SDK_STG_API_KEY exposure, but it still executes untrusted code on self-hosted infrastructure. Reject fork heads on this path, or route labeled fork requests to a runner isolated from trusted infrastructure.

Review comment at @.github/workflows/staging-tests.yaml around lines 35 - 36:
Update the `test-staging` labeled workflow path so fork pull requests cannot run
untrusted code on `infra1-runners-arc` or `runners-small`: reject heads from a
different repository, or route them to a runner isolated from trusted
infrastructure. Preserve the existing labeled path for trusted same-repository
pull requests.

Keep dispatch inputs out of Make recipe syntax.

project_common.mk still allows a filter such as foo; id to execute id as a separate shell command. Pass the test filter through its own environment variable and quote it at the final recipe boundary instead of embedding it in ADD_ARGS. This is a real command-injection defect, but it is not a major privilege-escalation issue because workflow_dispatch already requires write access and the authorized writer can run controlled branch contents.

Review comment at @.github/workflows/staging-tests.yaml at line 112:
Update the staging test invocation so TEST_FILTER is passed through its own
environment variable rather than interpolated into ADD_ARGS; in the
project_common.mk recipe used by make test-staging, quote the filter at the
final shell boundary while preserving the existing filter behavior.
