feat: mid-flow audio — transcribed text goes to NormalBot, not NLU

Browse Source 
When a user sends audio while in an active flow (__cap, __foreach,
collecting, __api_vars), the Whisper transcription is passed directly
to NormalBot as the step answer instead of going through NLU routing.

Bot still shows '🎤 Escuché: _texto_' confirmation before processing.
