fix(recordings): stop faking duration from file size + render edited content in search

The voice_recordings table has no duration column, but the backend aliased
duration_bytes = size_bytes (file size in bytes) and RecordingCard divided it
by 60 as if it were seconds — a 3MB MP3 rendered as a nonsensical '55924:3'
fake timestamp. Drop the fabricated field and show real file size instead.

Also render edited_content fallback in the analysis search results for
consistency with message cards/detail.
