fix(components): Record audio files incorrectly saved with .jpg extension

Record.convert_to_file_path() was using download_image_by_url() for
audio URLs, causing audio files to be saved with .jpg extension.
The same bug existed in convert_to_base64().

Added download_audio_by_url() and save_temp_audio() to io.py for
proper audio download handling, and updated Record methods to use them.
Also fixed base64 decoded audio to use .audio extension instead of .jpg.

Fixes #6853
Fixes #6509
