fix: property inspector - always show channels/sample rate, show 'default' if unknown

Browse Source 
- Removed duplicated/broken code from property parsing
- Always shows Channels and Sample Rate for audio nodes
- Shows 'default' if sample rate not available on node
- Latency shows ms calculation when sample rate known
- Added fallback: clock.rate, api.alsa.rate
