* fix: mirror voice config (stt/tts/voice) into profiles created via profiles.create
Desktop dictation is profile-scoped: /api/audio/transcribe resolves the
stt section inside the TARGET profile's home. Profiles created through
profiles.create got only a model section, so dictation and TTS silently
fell back to defaults (local whisper, often not installed) — 'voice
dictation doesn't work in bot mode but is fine in regular mode'.
Mirror the launch profile's stt/tts/voice sections (key-wise, never
overwriting sections the clone already has) under the same
mirror_credentials flag that gates .env/auth mirroring, and report it
as mirrored.voice in the receipt.
* guard: route voice-config mirror through canonical loaders
read_user_config_raw (write-back round-trip; load_config would merge
DEFAULT_CONFIG and no-op the mirror) + save_config under the target
profile's HERMES_HOME override — same mechanism as _write_profile_model.
Satisfies test_config_read_guard.
