Fix: Add id and htmlFor attributes to stream create form fields for accessibility

- Add id='recipient' and htmlFor='recipient' to Recipient Address field
- Add id='create-stream-token' and htmlFor='create-stream-token' to Token select
- Add id='create-stream-amount' and htmlFor='create-stream-amount' to Total Amount field
- Add id='create-stream-duration' and htmlFor='create-stream-duration' to Duration field

Fixes #631
