Adjust byte range calculation in server request handler. Fixes a bug …

…when listening audio.

This commit changes the calculation of the byte range to correctly extract the data. Rather than read up to 'end', it now reads the correct number of bytes, which is 'end - start + 1'. This correction ensures the right amount of data is read and processed.
