test(desktop): give the toolset-config-panel @/hermes mock the config-origin helpers

VoiceProviderFields now reads useHermesConfigRecord, which pulls
peekConfigReadOrigin/retainConfigReadOrigin from the '@/hermes' barrel. The
panel test's hand-rolled '@/hermes' mock predates those exports, so the two
TTS-row tests threw "No peekConfigReadOrigin export is defined on the mock"
and timed out. Provide inert stubs (no origin, identity retain); the panel
tests are not about write routing. Blank-line padding fixed by eslint --fix.
