Fixes#13399
### Issue
When viewing an audio attachment card in horizontal view, the waveform
was being clipped and not fully visible. In vertical view it displayed
correctly.
### Fix
- `audio-waveform` and `progressContainer` flex children were missing
`minWidth: 0` and `flex: 1`, causing container overflow
- `.affine-attachment-container` had a fixed height with `overflow:
hidden`
that cut off the waveform row
