These changes add explicit sample rate specification for audio transcription. A new constant defines the default transcription sample rate of 16000 Hz, and audio decoding functions are updated to accept and utilize this rate when preparing audio for transcription.

Changes

Cohort / File(s)Summary
Sample Rate Configuration
apps/web/src/constants/transcription-constants.ts		Added new exported constant DEFAULT_TRANSCRIPTION_SAMPLE_RATE = 16000 to define a standard audio sample rate for transcription operations.
Audio Decoding Integration
