Subject: [PATCH] test(fast-command): stub _load_gateway_runtime_config too

PR 2362cc468 ("fix(gateway): enforce env variable template expansion
on runtime config loaders") refactored `_load_service_tier` to read
config via the new `_load_gateway_runtime_config` wrapper instead of
opening `_hermes_home/config.yaml` directly. The
`test_run_agent_passes_priority_processing_to_gateway_agent` test still
only stubbed `_load_gateway_config` (the inner loader), so the runtime
wrapper saw an empty config and `_load_service_tier` returned None,
breaking the test:

  FAILED tests/gateway/test_fast_command.py::test_run_agent_passes_priority_processing_to_gateway_agent
   - AssertionError: assert None == 'priority'

Fix: also stub `_load_gateway_runtime_config` to return the expected
`agent.service_tier=fast` config, so the test once again drives the
priority routing path it was written to verify.

Confirmed reproducing on current main before the patch and passing
after.
