Event Details->Assets: Use human-readable units for duration, bitrates and sizes

Steps to reproduce:
1. Go to Recordings->Events
2. Open Event Details for a given Event
3. Go to Event Details->Assets->Media->Media Details (for example)

Actual Results:
Some values are displayed in units that are not suitable for human beings:
Media->Media Details->Duration: milliseconds
Media->Media Details->Size: Bytes
Media->Media Details->Streams->*: Bitrate in Bytes (or bits?)

Expected Results:
The UI should use units suited for human beings, e.g.
duration: Use [hh]:[mm]:[ss].[sss] instead of milliseconds
bitrates: Depending on the value, select kbps or mbps instead of bits per second
Size: Depending on the value, use GB, MB, KB, B instead of always using B

Workaround (if any):
