Fix Streaming Price

Currently, we’re summing up the prices that 100ms charges us for various features and billing the user based on that total.
For example, 100ms might charge us:

• $0.004 for conferencing

• $0.027 for recording

• $0.002 for noise cancellation

So we calculate: 0.004 + 0.027 + 0.002 = 0.033

However, users might not use all of these features — for instance, they may not enable recording.

We need a more precise billing approach that reflects the actual features used during streaming — such as whether recording or noise cancellation was enabled — rather than charging a fixed combined rate.
