Voice state was keyed `<platform>:<chat_id>` with no profile namespace,
so two bots in one Discord channel shared one /voice mode; every
`_voice_input_callback` was the bare `_handle_voice_channel_input`, which
(like `_handle_voice_timeout_cleanup` and the /voice slash handler) always
picked `self.adapters[DISCORD]` — a secondary profile's voice transcripts
were dispatched through the default profile's bot.
- `_voice_key(platform, chat_id, profile=None)`: named profiles get a
`<profile>:` prefix; default keeps the legacy shape (persisted state valid).
- `_voice_key_for_source` keys by the transport-OWNING profile
(`_adapter_profile_for_source`), matching what `_sync_voice_mode_state_to_adapter`
now restores per adapter via `_owner_profile`.
- `_bind_voice_input_callback` binds the capturing adapter into the
transcript handler (functools.partial); used at primary connect,
primary reconnect, /voice channel join, and `_configure_profile_adapter`.
- `_handle_voice_timeout_cleanup` takes the adapter it was bound to.
- /voice, join, leave and `_should_send_voice_reply` resolve the adapter via
`_adapter_for_source` (fail-closed) instead of `self.adapters[platform]`.
- #84872: `_start_one_profile_adapters` now calls
`_sync_voice_mode_state_to_adapter` on secondary INITIAL connect, as the
primary path and both reconnect paths already did.
