test(desktop): voice boundary test partial-mocks @/hermes and @/api/client

main went red after ae7bf98971 (voice playback threads the Bot owner scope
through api/client::ownerScoped) met 96cb6636d3 (the new boundary test):
the wholesale vi.mock of @/hermes drops setApiRequestProfile, which the
profile-scope store reads at import, and the @/api/client mock lacks
ownerScoped. Spread importOriginal() on both mocks so only the intended
seams are faked.
